Well finally I got enough pieces delivered to me to start the first amp and give a peek at what is to come so here is the beginnings of my next ST-120 project.
This pic is a mock up just to convey the idea. I am still working on getting the rest of the pieces down to the jungles of Costa Rica.
You can see the driver board is still unfinished and needs some caps and I am also waiting for the arrival of the quad cap and a bias meter.The SCM module as you see here is also incomplete. Mostly done but I still need some caps and a few resistors.
This is under control finally and Roy Mottram is sending some of it to a friend who will bring it down in a week or so.
Right now I am accumulating the funds to buy a transformer set from Bob for the first one and that should be all I need to finish it electronically.
After an email consultation with Bob I decided to use the C-17X chokes on the next ones and they are in the pipe now. The two C-24X chokes in the picture will go into this amp.
I was very happy with the quality of the plates from "Front Panel Express" they did a great job. I bought 5 chassis plates with three slightly differing concepts. All the chassis plates use essentially the ST-70 layout look.
The main difference is that they are a little deeper and bigger overall and some also have a slanted front panel. You can see the cuts for the 90 deg. bend to make flanges for the sides attachment which is still to be done.
After a bit more soldering its into the wood working shop to make the Cocobolo slabs for the sides, front and back.
I have a beautiful Cocobolo log I had sliced into 3" thick slabs and it has been drying out for about 8 months. I think its about ready for the saw and planer. Hope to send some more pics on this part of the project in a week or so.
