Rob - maybe we should talk. This just came out and you know how I am...
I figured (hoped) it was the cable from the crossover to the Dynaco,but that was wishful thinking. The pre-outs from the handy 1060 integrated and a different RCA cable proved that wasn't the case. I'm more annoyed at having to drag that heavy bitch out of an awkward location and into the garage and having no tunes than I am about having to troubleshoot and repair it! I swapped 7199's and 6CA7's with no change, so who knows what it is. That's going to wait for another day.
My first guess is a burnt resistor if you’ve done the obvious stuff already....It appears we only had one casualty Saturday - the left channel of my Dynaco ST-70.
I'll dig into it in the next day or so. Oddly, it was working fine until I moved it. As I recall, I had a dead left channel after recap. I poked around in it and didn't find any issues. I popped the tubes back in, and it's worked for a few months. I guess whatever I didn't really fix has come back to haunt me! I'll check resistors and tube sockets first. Worst case, I'll let a pro take care of it... I just don't like admitting defeat!
Ohhh.... Sounds like it’s just a lose wire or needs a solder touch-up somewhere. Should be easy.
I had my Jolida integrated repaired by their local tech (Ventura) recently because of a bad left channel. Fortunately it was just a burnt resistor and not an expensive transformer. The interesting thing is that the Electro Harmonix tubes, EL-34 in this case, failed short and caused collateral damage. He’s seen this often with all brands of tubes from that factory. Now it’s got a matched quad of JJ’s and sounds wonderful.
@toddalin never passes up an opportunity to rag on tube gear or vinyl recordsKind of makes one want to stay with solid state.
Except for that oh so smooth sound that tubes deliver. Although I had a baby Marantz 2015 that was close.Kind of makes one want to stay with solid state.
Maybe a double blind comparison should be in order for a future meetup. I myself have really taken to the sound of my Dynaco pas2 tube pre hooked up to my marantz 170dc. I enjoy the convenience and ease of the SS power and that pre adds just enough of that tube depth to please my ears.
Would love to. I'm not exclusive to tubes, it's just another flavor to enjoy. You like sand amps? Me too. You'll like my big Emotiva XPA-1L mono blocks. 250W Class A/B into 8 ohms and they double down at 500W into 4 ohms. The best part is I can flip a switch and run them in Class A for the first 35 watts with no audible switch to A/B above that.

Hey, better that than having to get under the hood David....
That's about as good as it gets David! Especially when you find it early on. Maybe we should have a spade crimping workshop too
Exactly. I'd be annoyed about this, but why would I be upset by not having to work on it?
As it is, I'm just glad it's back to normal. Oddly enough, my setup seems to sound better than before I disassembled it all last weekend. I think my speakers are positioned slightly differently, which may be the reason. As it is, I was really impressed listening to it last night.
LOL seriously! I used the crappy crimpers on this cable initially. I used the good ones last night, and I don't think this connector can come off without ripping the wire.That's about as good as it gets David! Especially when you find it early on. Maybe we should have a spade crimping workshop too
Good crimps are often over-looked, but key to the connection. My pair of Thomas & Bett's crimpers go back 40 years to when I was doing petrochemical automation and instrumentation. When you terminate a few thousand #14 control wires scattered all over a pipeline pump station you don't want to have to go looking for bad ones.
