Hello all 1st post, and thanks for allowing me to come aboard! I have a few questions.
So long story short, I found someone looking for D&A parts online, and thought maybe trying mine out, and selling it, but....I don't know what it's worth, and I might possibly have soft tubes?
The other day I brought it up on a variac, and proceeded frome there. I set the grid tune, put all controls to the midpoint area, pur her on high, and started to tune er up. With a Johson radio that hasn't been used in years, I was able to get 300 average out with 3w DK in. The meter I was using did not have a peak selection, and the Johnso also has a back swing ugh! I then turned on the 250W section and lost wattage, but low does about 90 on low, high, 300. All the while testing, my keyups were around 5 seconds, and at no time did I get any cherries (tubes).
I haven't used this thing in years, and frankly, now with old man syndrome, I don't really remember how to use it, however, I kinda remember something about the possibility of the tuning being 180° out, so I stopped.
I'm suspect of the drive section. I think it maybe soft? Is it worth fixing, or is the tuning possibly out of phase to cause the 250W stage to drop.
I don't even mess with CB amps anymore, so I am going to sell it either way.
What say you, any ideas what it's worth? To add further, all tubes light, SSB delay works, all caps are original, fairly good shape for the age. Thanks.
