Oversized caps (PS and coupling) in RH84: Problem?
I'm working on my Akai M8 conversion to RH84s (SE EL84) with 12B4 preamps. I picked up some unusual cap values, and now I started to wonder if they were the right choice. I have 330uf main PS caps (after the choke, before the separate dropping resistors to the driver and preamp tubes). I was initially thinking of the 220uf in the schematic. The 330's were a good deal, but some how it didn't occur to me that the 220uf was for both channels. So, I'll have 3 times the suggested value for the RH84. I simulated it in PSUD, and obviously I'll have less ripple. But, some folks criticize oversized PS caps. Will I have any troubles?
I also purchased oversized coupling caps. I wanted the famed and affordable Panasonic ECQ-P(U)s, but as they are now obsolete, Digikey is out of stock on the .22uf. So, I bought the .28uf pieces thinking it wouldn't be a problem. But, in searching for info re: big PS caps, I found that oversized coupling caps can be a problem with feedback loops. These aren't too much bigger, but as long as I was asking about the PS caps, I figured I'd mention this too.
