Was listening to a couple of days ago with a friend's Dynaco ST-70 which he had it recapped a few years back. He claimed that he spent some $$ to put in premium parts. Well that really paid off. Driving some JBL speakers, they really sound great. but he claimed that before the re-cap, the music was really unlistenable. Those ST70 he got were from the 70's and was never recap till recently.
