Just for a bit of clarification if anyone reads these old threads. The B-2101 amp and C-2101 preamp are not the same internally as the B-2102 and C-2102. They are similar but not the same.
The 2101 Series is not as built proof or as hardy as the 2102. I own 3/ 2101's and 2/ 2102's and I am intimately familiar with their internal parts and processes and only say that because I thought I had the service manual for the 2102 and I needed the service manual because they are not the same. I can't find that service manual and the ones on line say they are for the B2102 but the one's I have found are for the B02101's
If anyone has one or any updates to service manuals, anything at all... if you could please post it it would be greatly appreciated or drop me a note. I post everything I can find because as these things get older information becomes more and more scarce and it has on a couple of occasions had problems that have taken a year to figure out. One i just figure out and I finally took it to the shop and the tech charged me $450:nono::nono: to fix it and he didn't even replace the caps that had obviously boiled out. :thumbsdn:
To say I wasn't happy...
Thanks to everyone that posts to help your fellow audio geek seeing it keeps this great old gear State of the Art Equipment from the Golden Era of Analog to today.
