here we go!

Looks a little different... You dust it off or something

Nice redo.

Nice work! Still wondering how a guy with mad skillz like that could toss an amp like that in the first place. Perhaps alcohol was involved.

Keep it comin!

Very Nice restoration!

You sure don't shrug off a challenge!

 

[Dave C]

Turn it on and report back soon.

Oh it's been on. I ran it for a while at 100v on the variac but now I'm running it a line voltage, voltages are a little high as usual with old ptx's but it sounds nice like all these little amps do. I might mess with the feedback resistor and the coupling cap, currently I'm using a .01u between stages and a 6800R NFB resistor. I'm thinking about going to a .47u for the interstage, I have some .1u's but I think that may be too big.

Joe.

Anyone ever use a dual gang pot to adjust feedback circut? Seems like that would be nice depending on your source or type of music.

 

[Dandy]

Nice work Joe! What are you going to do with it?

I was given an AMI Continental II stereo power amp about a year ago that had been in a flood. It was rusty and nasty, but I was able to get it going again. The power transformer had an "electrostatic ground shield" that had shorted to the HV winding. I simply disconnected the EGS lead from the chassis, and the transformer worked fine. But, after using it for a year, the primary of the transformer recently shorted to the transformer case. I'm still using it, but I have to plug the amp into an isolation transformer. I wonder if the short was a delayed effect of the flood? :scratch2: Fortunately, the output transformers are fine.

Great sounding amp, BTW.
