This is what you said in YOUR post > "That appears to be the VTA board. You can get that on Tubes4hifi.com Nothing special! You can do it cheaper than $695. Just buy an older Dynaco ST-70 in good shape(most of them are) and get the board from Tubes4 hifi and install it. No need to further filter the circuit with bigger caps but they come on the board anyway. The power tranny is the true weak link to that amp but it is sufficient(that's all) for what it was designed for."
Before I purchased Bob's amp I did a cost analysis on all the parts in the amp. In regard to what you mentioned above. Especially "You can do it cheaper than $695." To do it right you CAN'T DO IT CHEAPER THAN $695 ...
Let's analyze what you said in light of costs involved. "Just get an older Dynaco ST-70 in good shape". On Ebay a decent Dynaco ST-70 goes for $350. If we then add in the VTA driver board and parts set at $99 now we are up to about $450. Now YOU SAID "the power tranny is the true weak link" and it is. Let's replace that with one from Triode Electronics or Dynakitparts > $120. Now we are up to $570. The quad cap is $35. Seven new tube sockets at $4.00 a piece is another $28 > Now we are up to $633. The gold plated input jacks are $15 and the two gold plated output jacks with FR4 mounting boards are about $20 > Now we are up to $668. Lets "assume" all the tubes are OK and we put it all together. Yes - It plays fine BUT the the hazy, rusty (and maybe pitted) frame is still there. A new stainless steel frame is $120. Now we are up to $788 to do it YOUR way AND we have all old tubes! Bob Latino's amp kit that I purchased at $695 includes a new stainless steel chassis AND all brand new tubes which include a matched quad of ElectroHarmonix EL34's.
If you now include a new set of tubes for your amp add maybe $70 for 4 EL34's, 3 12AT7's and one GZ34 to the $788 spent and we are over $850 for parts! Personally I don't know how Bob can sell the parts to his amp including all tubes and a new stainless steel chassis for $695 ?
