Daniel Barnum has generously given me a Jolida 502 integrated amp, which, if I can repair (he said just one burnt out resistor needs to be replaced), I'll be needing to buy a full set of tubes for.
There are so many different opinions, and, how do I sort out the listeners from the people that work for these companies who post in forums saying "this *** tube is great!"...
As far as I can tell, KT88 and 6650 tubes are interchangeable? I need a set of four, so I guess it's best to get a "matched quartet". I don't know why it surprised me, but I just saw today that Parts Express sells tubes!
Here are some I'm considering:
Electro-Harmonix KT88: http://www.parts-express.com/pe/show...number=072-809
Electro-Harmonix 6550: http://www.parts-express.com/pe/show...number=072-824
Sovtek KT88: http://www.parts-express.com/pe/show...number=072-494
I haven't even begun to research the other two types of tubes I need (1 pair of each): 2 x 12AX7A/ECC83 pre-amplifier; 2 x 12AT7/ECC81 power drivers
I am sooo curious to hear what this tube amp will sound like compared to my Onkyo receiver! I hope I manage to get it working.
I should bring the amp to a DIY event then we could do a solid state vs tube comparison?
