Palomar 300a customers working on the bench
Recapped, gone thru, cut diode traces fixed, loose ground screws and cold solder joints fixed, great set of tubes, Nomad Radio relay Keying circuit PCB installed and amp doing what it is supposed to do except the Nomad board doesn't have a Preamp so no preamp.
Only issue is should I address the mounting hole issue on the Nomad PCB or leave it alone? That mounting hole is not grounded, just holds the board in place. If it was a ground point, I would address it for sure.

Palomar 300a customers had me going for a few minutes
Просмотров 5727 часов назад
Yeah, another 300a. I know I said I wouldn't, but I said I would take this one on quite a while ago. I have a lot going on personally, and that's why I had recently took my RUclips site here down too. However, even though I am getting older and slower and 'losing' it, I still eat 300a's for breakfast and I was hungry for breakfast so I took this on. It had been recapped, but it was done badly. ...
Another Vintage Linear Amplifier Gotcha, check your Grounds.
Просмотров 241День назад
My junkbox Maco 300 stripping it down on the bench. Check your grounds. Never seen one this bad. Termninal strips are very loose. This amp would never work right with these grounding issues. I will drill these out, strip the metal back to bare, and then screw and bolt them down tight with a star washer.
Astatic D104 Mic with very rare early vintage unamplified 'GP' stand with VOX
Просмотров 140День назад
Just a walkthru of this early vintage Astatic D104 Mic with a very rare unamplified G P stand with VOX. It is so rare that I cannot find any info on this on the net. The D104 head on this Mic is a stock crystal D104 head. What's interesting to me about this Mic is the GP sticker on the base and the N V setting switch underneath. Since I couldn't find anything on the net, well, let's just open i...

Quick vid underneath and in action of the very hard to find Blackcat JB-440. Basically a JB-12 driving 2 JB-76 (200's) in one box. I was going to try to draw a schematic of this but it is so close that if you need to work on one, just look up schematics of the 12 and 76 and that should do it. 1 6BQ5 driving 4 6550A's. This is a swinging machine. The dead key can be dialed from 1-200 and it stil...

Tram D201A restore part 1 BA PCB rebuild
Просмотров 7714 дней назад
Refurbing a Tram D201A. I usually start with the BA PCB. It sits right next to the very hot running 6L6 audio tube. Too much heat is the main problem of D201 circuit board models and especially at the BA board. I replace the 2 watt carbon resistors with 3 watt flameproof and replace the 85 degree caps with 105 degree caps. On this one the bridge rectifier was bad too so it was replaced.

    I had a Palomar 350Z back in the late 70's and even then the output caps were trashed (seems to be a thing with Palomar). I had to replace those and two of the four 6LQ6 main output tubes. The drivers were still ok, and it would easily do around 500 watts on a 6 element beam antenna. Pretty nice old amps!😄
