You could put your 8 Ohm Resistor in line with your Digital Meter in 10 or 20 Amp setting which ever your meter has and read your Amperage on it to Compare. 16 Volts divided by 8 Ohm equals 2 Amps so 15 Volts should be pretty close to 2 Amps.

How did you figure out what Voltage and Amperage to order the Replacement SCR that you used? The new part shows to be a TYN416 which is a 400 Volt 16 Amp SCR and the Power Supply is a 26 Amp Supply.

You mentioned in the video that you have a copy of the schematic for this supply. Any chance you can send me copy? Cheers Bill w3kbs

Love the Bill. Beautiful rig very cleaned construction.

The camera is very close and things are not seen well, that's why I didn't like the video because I couldn't see what you were showing. For the rest, everything is fine.

This amp will eventually self-destruct The weight of the cooling finns will break (crack) the emitter resistors. Send it back to Crown and demand resolution for incompetence in design.

Beautiful but I would need a shower for sure

I have a very similar situation, except 6 times over, with a Heathkit PA amp AA-31. Tubes: 4 qty 6EU7, 7199, and 7591 outputs. I have some 7591s but no 6EU7s. Same conundrum, new ones are crazy expensive, buying used ones is very dicey. With your amp, you have only one tube to deal with, I potentially have 8 if I want to change the outputs to 6V6 or 6L6. I could keep it 7591 just fine. For the moment, I am just staring at it. I get the feeling it will wait for me. I am weighing whether to try to (a) change the existing circuit to 12AX7s, (b) just rip everything out and start fresh with a new Fender parts board, (c) sell the thing for whatever I can and be done with it. Right now: (c) is the most enticing.

Just bought this for 65$ I see a lot going for 2 or even 3x what I paid

You have to let it heat up before the green light will come on on the remote and then it will work

Someone left one of these by the dumpster where I live. Rescued the radio out of it and am now doing a refurb. It did work but needs a filter cap among other things. There were different chassis variations based on the suffix number. Yours is a -1 Mine is a -2 So far I've noticed a difference in some of the negative feedback circuits in the audio section between the two. Don't know why they had the variations. Gonna see how the audio input on mine works as a guitar amp when I get it done.

I love the video great job! I'm working on the exact same model right now for a customer. I'm adding bluetooth as well. The bluetooth module I'm using has Aux input which is connected to AM side. And don't need to use the switch in the back. The module automatically switches to Bluetooth when you press play on your cell phone.

You stand too close to what you are trying to show. HOW BIG IS THE TRAILER?

What just happened

Idk what some people are thinking sometimes when their pets are being a neusance and it's as if they're wearing ear plugs or think no one else can hear it? I mean I'd be embarrassed if my dog did that. It's like when you accidently set off your car alarm, and even though no one knows it's your car, it's fucking the most embarrassing 7 seconds pulling out your key and trying to shut it off before they're half way out of your pocket. Must have some serious issues going on in the household to be able to ignore it as if it's not happening, you must not be on speaking terms with the spouse to where you let it go on just to piss them off. Idk how else this sort of thing can be explained rationally. I mean if my wife hated when the dog did that and i was always the one to go outside and get it to shut up, you bet your ass I'd pretend to be asleep if it ever happened right after she pissed me off. No fucking dessert tonight? You let the grandkids have the rest of the ice cream bars? Good fucking luck sleeping tonight you whore. Scratch that, you put the grandchildren before ME? LET THAT DOG HOWL ALL MONTH LONG. : )

Get a mounting plate that screws to the wall with bolts that screw into the tv. Put medium thread lock on anything that can come lose from vibration and you'll never have to worry about the TV flying off. Shelves that have anything that can slide out just need a lip and you won't need to ratchet anything. If it works on work vans, it will definitely work on a camper.

I need 3 knob for model 217. Do you know where I can get them

Ty for doing this video.

Very nice..no stove no shower though

Sick

Nice set up

Duży i dużo tranzystorów mocy. Pozdrawiam

What was the SCR Part Number and the Amperage Rating - was it the same part number as the one you were replacing?

That is a beautiful build! Love the layout!

Crowns can take the punishment and keep going. I have a tri-amped surround sound system. I use a PS 400 for subs, a ps 200 for front left and right JBL L100 speakers, a D150A for the JBL 4010 studio monitors, a pear, for center speakers. And a D40 for the rear surround sound speakers. It's been fun and sounds great..

I have this same one I found at a thrift.. It stays stuck in cassette mode.. player actually works but the radio doesn't come on when I eject the tape..

Do you have a sound comming from the relay at the back on idle?

The transformer and that you go the rectifiers. You might want to check those replace the rectifiers. Also, it can be the capacitors that controls the fan. Don't know if that one has a fan. Please let me know. Gunny, USMC

Did you replace the rectifier?

Widow maker....but that's ok! Plug into an off board 1:1 transformer and your good

7868 is one of my fave sounding tubes

Like the rear bathroom (away from the kitchen). Great design.

No shower?

Beautiful build. I would need a shower space

Love the bench to sit and read the bible 🙏🙏

The Toastmaster brand is unfortunately built cheaply. These used be great products back in the day. Now a new company builds them cheaply. I have 4 Toastmaster products in my house. They are reliable just cheaply made. I put a scratch on my Toastmaster toaster just cleaning it.

Looks nice, curious what size trailer is this?

Very Nice!

Interesting. Some random comments from someone about the age of that radio: I was amused that you referred to it as a "stereo". Almost everyone would these days, that term is ingrained in our consciousness. But it isn't stereo, it's mono. Stereo sets wouldn't start to come along until the early 1960s. The little white tube with wires wrapped around the ends is a very low value capacitor, on the order of several picofarads, or, as they would have said in those days, "micro-microfarads", abbreviated mmf, rather than the pf we use these days. Absolutely no reason to think that it would be bad. The burning you saw on the cap near the orange replaced cap doesn't necessarily mean that cap was bad. What happened was that the original of the replaced cap got hot and burned up. What you are seeing is collateral damage on the other cap, but that discoloration would probably not have been enough to cause problems with it. (All the paper and electrolytic caps were likely bad now and needed replacing. But when the fried cap was replaced with that orange cap originally, the other paper caps were likely still usable.) The back-to-back bumblebee caps were obviously a replacement at some point in time. Probably another paper cap that went bad. Probably not done at the same time as the orange cap replacement. The way the wires were twisted together shows a real amateur did the repair, as does the mismatched foil ends of the caps.

great work

I have an inverter made by them. It's supposed to produce 200 watts, and I believe the operating frequency is somewhat higher than 60 hertz. It uses a mechanical chopper.

i just picked one up on freecycle and it is a gem. I may replace the metal front with cloth.

It's working, the volume drop is normal cause it acts as resistance/clipping. If you put it before the transformer, with the right resistance set up, it should work similar to a tube, but with a tiny opto compression aspect.

4 months of no machine! Was searching to buy a new one, and was going to throw this one away. This FIXED IT!!!! Thank you!

Lifesaver! I didn’t have the same volume problem but I needed to know what the inside is supposed to look like to figure out what was wrong with mine. It seems like there are no pictures of the inside of these radios on the internet, only this video. Thanks so much!

If you connect the negative feedback to a switch like that… (I’m not electrical engineer so I know nothing about this) but is it possible to use a 1/4” jack to use a fender style footswitch to activate it like a boost switch?

How has that brand held up? About to do an install on mine.

have you ever heard of a tuner?

Thats a 10 inch speaker i think or i have the wrong amp.

Definitely my favorite layout, looks like you could/can be comfortable. A lot of these just seem like it would be "non cozy" lol. Don't get me wrong people do beautiful and creative work with great skills and imagination but for me this is "IT". Sorry for rambling i hope you guys are enjoying it...
