it keeps exploding this is the third one i assembled send it back i have no way i have a bot 3 or 4 of them can you send you 1 that is working

I decided to only use a 18VAC or less transformer as all the other mods seemed overly complicated to me. 24 VAC is too much for the powered op amps and will eventually go away. I replaced the 24v regulator with a
