Hi Everyone,
Resurrecting my old college system and found this site doing research on the Van Alstine external power mod for my Harman Kardon T-60 and interested in learning more if any of you have attempted it.
System components: HK T-60 (Shure V15 V, Ortofon 10, Denon 103R), DBX route selector an encoder, Denon CD, HK CD301, HK PM655Vxi, Teac X-1000R, Polk RTA 12 and Monitor 2's, Koss ESP 9's, HVL 1c's and AKG 340's.

Best,
Mike
