I'm looking to put in new tubes in my JCA20h soon, but I don't know tubes all too well. Can anyone tell me what are some good tubes to put in? 3x 12AX7 Preamp / 2x EL84 Power are in it right now stock. Noticed one of them have a China sticker on it.
JJ in the power amp, and probably in the preamp too, unless you want brighter, then go for Tung-Sol.
