I did a search on this and only found some general points about putting EL34s in a 6L6 amp. I am hoping someone can tell me specifically to this amp. I had a PRS SE-50 that I liked a lot and wished I never sold (I moved to an apartment but now I have a house). It had EL34s. I am having a hard time finding another one, much less at a decent price. I am finding a few PRS 2-Channel H models, which seem to be the same kind of amp but with 6L6s. The 2 Channel C model has EL34s. There are bias jacks but no switch between 6L6 and EL34 like an old Mesa Rectoverb I had. Does anyone know if I buy a 2 Channel H model, can I put EL34s in it? Obviously I should try to find a C model but between the Emporium, Reverb, Craigslist, Offerup, and Ebay I have found many H models but no C models. I downloaded the manual and it doesn't say anything about switching out tubes.
