I agree with the above post. I too have rebuilt these amps and would also look into the Joe Curcio board for the ST-70 .Curcio designed all the original Sonic Frontiers amps and if you are looking for a rebuild with GOOD bass response and very clean extended highs, check it out . The curcio board gives it a very Modern sound using 6dj8s, not at all traditional 60s Dyna however. on the web at Curcio audio engineering. He also offers a board that does away with the tube rectifiers, which you will hear alot of controversy about.

Hello, I am considering the above combo, this will be my intro to tube amps. I had planned on going with the total rebuild kits from Van Alstine. What is your honest opinion on this route, what interconnects and speakers do you suggest for this combo with classical music at lower levels in a 13 by 15 room ??? I have also considered a CAL Audio ICON II for a CD player, are the Wadia's really that much better???
