I bought a new Decware first new thing in 5 years, then it was class D amps before that. Before THAT it was used Mac gear. 100 pieces of gear 3 newer pieces are still 7 and 2 years old. Everything else is OLD, maintained and if need be rebuilt.
I watch out for the yellow cap crowd too. Macs just don't sound right with polies vs PIO rebuilds and then know what to put in. No need for fancy high dollar caps either. Good resistors Russian surplus PIO caps work the best for most Macs. The PS and a few spots and types of gear like the MC225 you can ruin by changing the caps, they don't go bad very often.. PS is a different story..
Fun expensive and life long habbit/hobby for me..
