I found a very clean ST70 which had the can cap replaced otherwise original. It was equipped with EH brand of big bottle 6ca7's I guess when the last owner lost the main cap. it damaged the left rear tube. Anyway, to make a long story short I am not sure if I will want to resell or keep the amp but in any case the power tubes will need to be replaced.
I am looking for ideas on replacement tubes. I could just add 2 new EH 6ca7, or buy a set of JJ EL 34s, what about 6L6's or KT77. My main problem is I don't think the EL34's have enough Bass. I like the sound of KT88's much better, {The reason I may sell the amp.} The tube needs to be reasonable in price and something the next buyer may want. Any ideas?
