It's one of these. The shot from the back.....makes the OT look 3x bigger than it really is. I took out the can cap...probably going to use 3 Radials and Term Strips, just because i have them laying around. Not going to do anything (permanent) that that would "Devalue" this piece of junk. Do not und...

Yes...i hear what you are saying.
This amp lay-out is not set up well.
Tube sockets in middle of chassis.
Power tube socket is V2.
Was made with a Can-Cap
etc etc
So it is not the easiest amp to wire per standard intelligence.

Wow...OK.
That will make my life easier. Not a whole lot of room in this chassis.
Thanks Again

I am working on a Friends 1421, his is actually a Sears 10XL. It is, kind of, a cheap point to point mess. I am trying to clean it up, do a cap job, improve the heater wiring, etc etc. I have Never Heard one of these amps. Have no idea how Quiet/Noisy it was. The OT is the size of a quarter...seems ...

I suppose he is what you would call a "gifted player."
He CAN play electric, though I have only seen it once, I believe, on Youtube.
Hard to remember exactly.....but I think he was on stage with Bill Kirchen, and both were playing a telecaster.

Yeah...Thank You. I was wondering about those (typically 220k) resistors. I Think this is the first time I have ever seen this rectifier, and the first time I have ever seen a "bridge" rectifier used with a PT CT. I did not even notice the screen voltage.....never really looked at an Orange schem be...

.....Are you still saying that is a bridge rectifier.?
Thanks

Do bridge rectifier use a CT Transformer.?
The link does not work on my computer for some reason.
Thanks

Man.....what an impressive looking build.....the orange is spectacular. I guess I am lost on the rectifier. Is that what is called a Two Phase.? Is that the normal way the diodes are grounded.? Thank You Very Nice job....like the idea of using "just" 2x EL34. I sure do not see many of these getting ...

Always enjoy looking at your Work/Builds.
What are the little boards you use.? Are they conductive on one side, or are you wiring them.?
Thank You

Not that I have much experience with this stuff.......but that is the first "Magic Eye" that goes in a vertical or horizontal, that I have seen.
Was that common at one time.?
I have only seen (the few that I have) the round iterations.
Very nifty looking build btw.

All true. That's why I'm setting up a repair station at the multidimensional crossroads of AES, Newark, Mouser, and McMaster. I'll pull my own parts as needed, and it can go on my tab. Oh Christ.....I'm a sick puppy. I will, sometimes, peruse McMaster-Carr even when I do not need to order anything....

Here's what he did:

-checked pre-amp tubes

-caps changed (not the cap cans)

I am NOT saying this is your cure, but anytime I see the word "checked", I always wonder the same thing.....how did he check them.?
Others have said, but if the can caps are original, or 20 years old.......
good luck

I trust you.
What brands of new caps have you checked, how many, and what were the numbers.?
Thank You

Guys really get hung up about caps, don't they.? It seems to be the amp equivalent of motor oil for car dudes. :) Nichicon IC Xicon F&T Panasonic etc etc I have used a lot of IC and those "generic" caps from CE for quite a few years with no trouble. With the exception of the CE "brand".....prices se...
