I got the ones at Ebay. They are OK. 3-4 weeks to arrive thru USPO.
I am having a bit of problem with the MJ15025/15024 version of PSU (re-testing and substituting components after an accidental short between +22 and gnd). Does the components without heatsink get warmish after 15 min without load. On PSU, I noticed that PNP and NPN and lm4040 diodes can get warm/slightly hot (how high?). Second, the short happened when amp was connected. Do you think I damaged any component on amp. Thanks.
