Well here is a bit of a recap on what I had to do -
Picked up 3 MKIII Ebay specials, really ended up all in bad shape upon arrival. They were factory assembled versions from what it looked like due to rivets on the tube sockets. They had been hacked up pretty good with some new caps, but still not something I would have plugged in.
Chose to do a full overhaul, saving really only the power transformers and the power cord!
Picked up most of the parts including the nice stainless chassis from DynakitParts.com and driver boards from TriodeElectronics.com
McMaster Carr supplied the stainless transformer bolts and kep nuts, and the fiber washers. Home Depot had the granite gray paint and satin black, cloth wire from TubesAndMore.com
Stripped and painted Transformers, let the bells dry for a bit next to an old electric heater. The very dirty and transformer cores were cleaned with a combination of scotch bright and sand paper where badly corroded. Masked off most parts, and bolted them together with old bolts prior to painting. Painted first with a light coat of black primer, then after drying, shot a light coat of Satin Black paint. Let them dry for a while since I was slow at the next step.
Assembled the Triode driver board, then basically followed the Dynakit instruction to wire up the amp, which was pretty straightforward, the Triode driver board has an over abundance of instructions for those that want to modify it, but after getting through that it was very simple to wire it into the Dynaco amp. About the only thing that was different was a couple of wire lenghts, other then that the numbers on the board match up to the original Dynaco's and easy to wire up.
What's left? I have the original covers that are in ok shape and may just give them a cleaning and be done with it. It was amazing how nice the covers were compared to the amps (Which means they may have been just pieced together).
And on fire up tubes filiments glowed orange, tossed in the correct bias and nothing exploded, smoked or turned red, so success it seems.
Tubes are JJ KT88's and ECC802S in the Driver with the a JJ GZ34 rectifier
And that is the story with these amps. This is my second tube project, the first was my ST120 from you know who...
And one thing as a side note from the money spent perspective, I likely would have been better off just picking up a pair of NEW MKIII's from Dynakitparts.com and saved a bit of time with the transformer clean up and would have spent about the same amount of money since I could only reuse the transformers and amp covers when all said and done.
What next? Possibly an ST35 or a Grommes 260A from scratch
