RE: Confess your DIY amplifier sins here.....



Kept in a drawer for 14 years audio note kit 4 6V6 stuffed board counting that someday a pair of used OPTS pop out and they did a couple of months ago in Hungary . (I was too cheap to order from Peter ) Spent a couple of days assembling the whole shebang in par metal enclosure. Fck it always looks so simple and easy than it stretches to hrs and hrs ...Din't check beforehand if the board works because I remembered it worked 14 years ago when I put all those new panasonic and cerafine caps and checked it out. After assembly
one channel was distorting badly so I disassembled it (not easy with this ed it type of amp and checked it out , all was Ok and static operation points and voltages were spot on Wtfc?? I fire up osciloscope (first time in 3 years;( and started poking around almost frying that damn thing but apparently that offending channel was distorting on the OPT . Uhh,... ficking Hungarians sold me a bad trans me thought (although the trans was a year old , quite pretty with copper shrouds and big for 6V6 amp, clearly a winner AN (UK) quality) devastated I put it on the shelf for two days than returned to it to discover that I hooked up the the CT of primary to one of the plates ...I happily put the cover on to discover that I really should have payed $15 more and order a fully perforated one.. I loved the sound from the first note . Must be the best cheapo amp I heard although it's circuit is seemingly more complicated that it really should be.
I like it so much that it deserves full choke input with Lundahl Power and choke iron which it will get ones I cure my nerves a little . There is more to the story , much more but I don't want to look like a complete moron hehe...
