Here is the thing with the caps. I am finding that my dmm won't check the larger values and it certainly does not put them up to working voltage, so I don't think that is going to be useful data. I was just considering putting the old ones back in that channel because I cannot confirm there may not be a defect in one of the new ones, but I can confirm that the circuit worked before all of this with the old ones. That's all. I am starting to get really frustrated with this thing. I was enjoying it so much. Never had a recap go sour like this.If the new caps are ok, I would left him in place.
Regarding shotgun H701, 703, 705, 707... well, at least we are be sure that those are not the culprit, and must be something else right?
How about resistors? You can check them on board.
Let's see what someone with more experience says.
Fair enough, you can check if they are shorted with you DMM the Ω function.(just in case) but you probably know that.but I can confirm that the circuit worked before all of this with the old ones. That's all
Be patient, frustration sometimes is part of the game, take a break... you'll see that someone with nice experience will chime in.I am starting to get really frustrated with this thing
Thanks for that. I know it's all part of the game.Fair enough, you can check if they are shorted with you DMM the Ω function.(just in case) but you probably know that.

That's what I think too... I've never had problems with new caps taken down outputs, just old caps and hums. And if they are not shorted.... I don't see problem.Probably replacing the transistors was the true fix since when an output shorts it can take out the supporting drivers with it,
Glad you got her up and running again. they ain't making no more of them ! Saved another piece of vintage gear and Marantz at that. Great sounding equipment.I think that's a safe bet. I put the new caps back in and all is still fine. Sounds good, bias sets right up and stable. Only issue have now which I'm going to start a new thread about is the dc balance/clipping adjustment. Thanks for everyone's suggestions.
