Should you clean the tubes off with isopropyl alcohol first to remove fingerprint oils??
No not needed. You are thinking of certain types of light bulbs
I'm in Indonesia. I'm not shipping my 811H. Can you tell me what gas discharge tubes to use please?
150 volt
Is the amp wired for 220 vc just looking at the jumper arrangement
Yes
Good work as always. Happy New Year 🎉
Thank you and thank you for watching Happy new years also
Happy New Year Scott🇺🇸🎇🎆
Happy New Year to you also 😁
Good work 👍⭐️
Thank you for watching and for the compliment
Welcome back. 🎉
Thank you
When replacing the bleeder resistors, do you take out the whole board and solder from the bottom, or do you just clip out the old ones in solder to the remaining leads?
I un solder from the top, clean the holes install new resistors with leads near flush with bottom side of board hole. I flow solder through top of board so both sides of board are soldered to each lead. Not a quick job
Just curious. What did it cost to repair that amp?
About 50 cents
Happy New Year. You need a break. Awesome Video. W9BBW
Thank you Happy new year , just getting some house stuff done Back to work on Monday 😁😁
You need a break
Got that right I’ll be doing some non amp stuff / house stuff but will be back at the amp and harbach sales next week.
Have a hard new year friend
Thank you , have a happy new year also 😁
Enjoy your time off and have a happy new year 🎇🎆🎉 p.s. Agreed. As long as parts are available, those amplifers will be around for a few more decades.
Thank you, have a happy new year also Have house stuff to get done and then back at it. Parts won’t be going anywhere
My 220 is working like a champ, Scott. Thanks so much and enjoy your break!
Very welcome , thank you for trusting me. House stuff to get done , relax a bit then back at it. Many more years of pa repairs and Harbach kit sales Have a happy new year
Hi Scott, The SB-221 I'm converting to a 220 still has the original Eimac tubes dated 1979. The only time the tubes were used was when I completed the SB-221 in 1979 and tested it. The amp was never put on the air. Do you have a service where I can have the tubes tested, or just get a set of Penta Lab tubes? Have a Happy New Year and stay safe. 73 WJ3U
I hi pot them when a customer sends a package in for repair . If yours have not been used then most likely will be gassy. I would just buy a new set from penta directly from penta for the best price. Have a happy new year
I love your videos
Thank you for the compliment and for watching, many more to come Have a happy new year
Get your rest in Scott! Thank you for all of your help! Heres wishing you a happy new year! 73
Very welcome , lots to come in 2025 Have a happy new year 😁
Would like to replace the lamps on mine for the meters, can you tell me the part number and manufacturer for that? Thanks and happy new year.
Sorry I do not have a part number or manufacturer , I had obtained from Ameritron Happy new year also 😁
I recently picked up a single tube 3-500 amp (vectronics 600). It came with a spare tube. Would you recommend swapping them out in regular intervals instead of the spare never being used? Enjoy your time off, 73.
Sure , maybe every few years. Must get the anode hot can’t just run the filament. Happy new year
Good Work by the way.
Thank you for watching and for the compliment Have a happy new year

Thanks for presenting informative videos about your high quality work. I've watched a lot of your content, feel motivated and informed by what you present, and know I can turn to you for applicable amp repairs as needed. Thanks again and Merry Christmas to you and yours. ~ 73 ~ AC7WH ~ Jared
Thank you for the compliment. Feel free to call if ever have a pa that is in need of service. Have a Merry Christmas also 73 😁
Thanks for the video, Scott. I've been searching for an updated schematic that shows this mod but have come up empty. Your close-up videography, and explanations, sealed the deal. I have to say, though. That whole "bend a hook in the lead, then solder" approach, that Heathkit had, makes desoldering cumbersome. I found it easier just to clip the hook, with flush cuts, then reflow it and the lead pulls right out. But you have to fish out the clipped "tailing".
Great video and workmanship! Merry Christmas!
Thank you , Merry Christmas to you also 😁
Hello and a Merry Christmas to you and your loved ones.73 Leo.

When replacing C4, do you go back with an original 20uF / 160V cap? Or another value? I've seen 47uF used in another restoration. Just prepping for an upcoming new addition to my shack. 😉
I use a 22 uf , 160vdc 73
