This thread was started in 2004 and I was curious who might have posted in 2004 who is still posting today (no secret that I’m retired and have time on my hands!). Anyway, the first post I found was made in August 2004 by @sbank aka Spencer. I stopped after I recognized the first one. Anyone else been posting to this thread for 17 years? Way to go Spencer! |
@nicks25 , @noromance , lol. Yeah @slipknot1 is one of my favorite people in the world. We built my rack together, listened to music hundreds of times, shared many a meal & drink. We both spent many years helping lead the Philadelphia Area Audio Group, a non-profit club that has grown and prospered.He retired, moved to somewhat remote VT mountain location, downsized his system and large lp collection a bit. He kinda tuned out to tune in.I owe him a call! Cheers, Spencer |
@boxer12, Tim, I was listening to Bardo Pond “Volume 2” earlier. My copy looks like a translucent military fatigue. Excellent stuff, by the way. You might want to look into this, Amyl And The Sniffers “Comfort To Me” ATO Records Australia 2021 Ten Years After “Watt” Deram/London 1970 Savoy Brown “Blue Matter” Parrot/London 1969 Talking Heads “Remain In Light” Sire 1980 Phew “s/t” Pass Records Japan-reissue of this 1981 record coproduced with Holger Czukay Nomad “EP TWO” Curved Pressings 2021 the The “Soul Mining” Epic/CBS 1984 |
....so many records to listen to then the amplifier died!
Got out the meter and discovered a shorted coupling capacitor.
But, that involves ordering a replacement which will no doubt take a week.
Fortunately the amplifier design incorporates protection for the 300B triodes. When I went over to check why one channel went out, the grid in the 300B was already red hot. In an instant, the protection disabled the filament protecting the 300B.
So, it will be a quiet few days until the replacement capacitor (Jupiter if anyone is curious) arrives.

Oh man, that sucks. At least you figured it out quickly, and the tubes are OK. Have a back-up? I've always thought I should have kept my B&K amp as a back-up instead of selling it after buying the Belles. Now I routinely look at the same/similar amps in the US Audio Mart listings just for that purpose. |
@puffball08 Curious why a Jupiter (wax?) cap would short out. Too hot in there or too high a voltage? Edit: maybe the Jupiter is the replacement... |
@bkeske -yes, I do have a pair of home made monoblock amplifiers if I decide I need music back quickly.
Actually, I have 250~300 more records in line for the 3 step cleaning process. I may just concentrate on whittling that down a bit while waiting for the capacitor.
@big_greg -I built both amplifiers. One from scratch, one from a kit. So when something goes POOF, it's out with the Fluke meter and Tek scope. Fortunately the POOFs have been quite rare.
@noromance -Yeah, it kind of puzzled me as well as why the Jupiter cap suddenly became a 0.04 ohm resistor. The amplifier has 4 stage coupling capacitors, all Jupiter foil and wax. I also used Jupiters in the scratch built (based around a RCA 811A triode) without any problem. I'm thinking there might have been a void or imperfection in the kraft paper layer which allowed a pin hole to form between the copper foil layers. There have been some strange clicks once in a while from the channel that finally died today. It may have been early signs of the capacitor failing. The capacitor that failed is rated at 400V in a circuit operating at 130V. I hardly think the AC component of the music would get anywhere near 400V. And even if it did, Jupiter tests each capacitor at 2x the marked operating voltage. I will send them the defective capacitor and see if they can figure out what happened.
@boxer12 -You're welcome Tim. Enjoy! If you're a fan of Swell Maps, definitely check out the new compilation of old and very rare tracks covering almost their entire lifespan in the double 12" "Mayday Signals" on the Easy Action label from the UK. The distributor I bought it from in England ran out already. They'll go quickly.
