I've got an Atlas 215 that needs caps replaced and I'm getting ready to do it. My skills are marginal, yet watching you work is the best training one can have. Thanks Buddy!
Thanks for letting us peer over your shoulder in the shop Buddy. Always something new to learn from you! You should finish the job on the Eico 324 then give it away to a viewer. I've got a working recapped Triplett 3432-A signal generator and the only thing I need to replace is the RF Output jack. It did come with it's original probe with a matching plug that also needs changing out to a BNC too.
Nice job! I have one of these because of one of your earlier videos. Caps replaced, tubes tested, and switches cleaned, but I need to do some further testing to see if I can clean up the signals. Thanks for sharing.
@@TheRadioShop I added another stage to the RC filter. Lowered voltage and ripple. Oh and its a bridge rectifier ( 4 diodes) . used another of the same value resistor/capacitor for RC filter thats there already.
Hi Buddy Just stopping by the shop and checking in. Good to see you at the bench. Always learn something listening to your careful narration. Wish I had your ability. My best to you.
Nice video again, Buddy! Always pleasant to listen to your calm and clear style of narration. Would love to see that thing restored to its former glory. Thanks for sharing!
I love your videos, best teacher around.I hope you put the item in one of your contest .but I am sure you have many friends who could use too.thanks for your video .
Yes. Complete it and give her a bath. Love seeing old equipment like this ressurected and put back on the bench. Another superb video as usual, Buddy. Thanks for letting us watch over your shoulder. 73 de K7RMJ Frank.
Great cideo Buddy! I have a TEKTRONIX 321 and I recapped it but the big filter caps were goon and high quality so I left them alone. My scope works okay but like all scopes I have the DC balance changes when I select differant ranges on the volts per div dial, the base line moves up and down. I would like to see a video on that problem. I also have the EICO 324 and it works well, the tracking is off so I set the ranges in the middle frequencies where they are spot on but the upper and lower ends are a little off but I use a counter on it anyway so it don't matter.
Good idea on using a counter Bill. That does help a lot. Unit is already boxed up so cannot make that video for you, sorry. If I ever get my hands on another one I will show that. Thanks for watching.
To double the voltage you need to put then in series, which is then 1/2 the cap value. Also if the caps are different values the voltage will on each cap will be a ratio of their values. if they are the same value the voltage will be a 50:50 split. Still a nice video and enjoyed watching it.
Jacob, we will probably never finish the 101 series as there is so much more to cover and I dont think I will live that long. But yes there will be a lot more video on the 101 as soon as I can get to them. Thanks for asking.
@@TheRadioShop if you do get a chance, the VFO clean up/lubrication would be extremely helpful. I have been unable to find any info on this. Thanks! Keep up the great work!
Hi Buddy. Nice video, as always. Question: Where did you obtain that battery operated solder sucker? I want one. It would save bench space in my small shop. Thanks and 73, Bob, K5INW
Please do and post it. Thanks. Even if it has an AC cord, it's still a lot less unwieldy than other options. I enjoy your videos. Did you get all the problems fixed with your IFR1200? I am solving mine one at a time !!! (Yeah, but lately, a bunch of problems have attacked me at once!!!).
The silver solder is required when soldering to the ceramic standoffs as the metal layer is silver that is bonded to the ceramic. With non-silver solder and/or too much heat, the silver delaminates from the ceramic as the silver leeches away from the ceramic into the solder. The are a very reliable construction method and basically never wear out, as long as you use silver solder (3% silver) and use as little heat as possible when soldering.
Is that a RCA Nuvistor just above the double row of trimmer caps? And like another viewer said, paralleling up two caps will simply add the values together. Don't feel like the Lone Ranger though I made the same mistake the other day teaching a General upgrade course but caught myself (luckily before the students did!). Nice work as usual Buddy! 73 - Dino KLØS
@@TheRadioShop no worries, it happens. The only risk-issue with paralleling caps is that the original cap may eventually short. I personally think that risk is slim based upon seeing hundreds of examples of this being done by previous techs and never once seeing the original cap short... but certainly the right way to do it is to remove the old cap from circuit.
Mistake on capacitors. capacitance of capacitors in parallel double.
Good to see you back in the shop Buddy. How I wish I could find as many equipment bargains here in the UK!
Excellent on the silver solder. I'm impressed!
I believe 2 caps in parallel twice capacitance. Love your vids!
Thanks and you are correct.

Cool deal Mike. Just do one at a time and you will get through it. Thanks for the comment

Cool on the Triplett, changing to a bnc is always my first priority, this way all my standard cables work. Working on part 2 now. Thanks for watching.

Have the same unit. works fine. after I replaced the capacitors and added a full bridge rectifier!
Nice on the full wave rectifier. Were you able to keep it close to 110 volts on the B+?
@@TheRadioShop I added another stage to the RC filter. Lowered voltage and ripple. Oh and its a bridge rectifier ( 4 diodes) . used another of the same value resistor/capacitor for RC filter thats there already.
I'd like to see it aligned. Then give it away.
Working on part two now.
Good to see you Buddy.👍🏻🇬🇧
Thanks 👍
Hi Buddy

Thanks Ron, working on part two now
Neat old signal generator. I had one many years ago same model 324.
They do pretty good for what they are. Thanks for sharing
Great video, l fondly remember my old friends Model 324.
Thanks for watching
Hey Buddy, you were thinking of capacitors in series in relation to the capacitance halving.
Yep, I get it backwards at times. Comes with getting old.
I've just learned recently from diodegonewild, those caps across the primary on the transformer would be providing some power factor correction
I have that same model signal generator. It's all original and definitely needs new caps but it's far down on my project list.
Nice, will not take long to recap. Quick and easy.
Nice video. I have one of these on my workbench.
They work fairly well. Thanks
Yes. Complete it and give her a bath. Love seeing old equipment like this ressurected and put back on the bench. Another superb video as usual, Buddy. Thanks for letting us watch over your shoulder. 73 de K7RMJ Frank.

In words of Mr Carlson's Lab, those are foil and paper capacitors, they are outa there, no questions asked!
To double the voltage you need to put then in series, which is then 1/2 the cap value. Also if the caps are different values the voltage will on each cap will be a ratio of their values. if they are the same value the voltage will be a 50:50 split.
Still a nice video and enjoyed watching it.
You are correct, sometimes my mind gets reversed. Good to see folks take notes. Thanks for watching.
Ótimo dia trabalho gualidade total bazuka Foz do Iguaçu pr Brasil
Thanks
Could you please link to where you get the capacitors? I find it hard to find good replacements. Thanks. 73 de ZL2ALW Andrew
Andrew, to name a few: "Just Capacitors" out of Canada, Sals capacitor corner, Mouser,
Any plans to finish the FT-101E series you started?
Jacob, we will probably never finish the 101 series as there is so much more to cover and I dont think I will live that long. But yes there will be a lot more video on the 101 as soon as I can get to them. Thanks for asking.

Hi Bob and thanks, it is not battery operated, has an AC cord attached. Not a bad little unit, let me see if I can find the link for that on Amazon.
Please do and post it. Thanks. Even if it has an AC cord, it's still a lot less unwieldy than other options. I enjoy your videos. Did you get all the problems fixed with your IFR1200? I am solving mine one at a time !!! (Yeah, but lately, a bunch of problems have attacked me at once!!!).
Just wondering, why can’t regular solder be used to replace components soldered in with silver solder?
The silver solder is required when soldering to the ceramic standoffs as the metal layer is silver that is bonded to the ceramic.
With non-silver solder and/or too much heat, the silver delaminates from the ceramic as the silver leeches away from the ceramic into the solder.
The are a very reliable construction method and basically never wear out, as long as you use silver solder (3% silver) and use as little heat as possible when soldering.
The comment below is spot on. Good question.
Stray capacitance in the Eico 324?
When connections are dirty yes. And lots of harmonics.
Is that a RCA Nuvistor just above the double row of trimmer caps? And like another viewer said, paralleling up two caps will simply add the values together. Don't feel like the Lone Ranger though I made the same mistake the other day teaching a General upgrade course but caught myself (luckily before the students did!).

Hi Dino. Yep you are correct, two Nuvistors in this unit. And yes mouth was moving but brain not engaged. Sad pad is I missed it in he edit...
buddy, caps in parallel are DOUBLED not halved.
That is correct, my mistake
