I prefer Sovtek KT-88 over Svet 6550C and Svet KT-88 over Sovtek KT-88. However, I prefer Penta KT-88 over Svet KT-88 and their price is somewhere between Sovtek and Svet. Since you are using 6550C, the Sovtek KT-88 would most likely give you satisfactory results. However, if I were You, I'd pay little more to get Penta. However, if your amp were voiced exclusively with 6550C, all bets are off.
KT88s...the final chapter
Ok, Ive posted before, ive read the prior threads, ive read the David99 vs Marchman debacle, I done my homework on NOS, Valve Art, Svetlanas, out there. Id love to use Gold Lions and other NOS out there, but most are sold on ebay 1 pair or quad at a time for around $100 a piece. I need 16 tubes. Svetlanas run about $40 a piece. Sovteks are about $24 each. My question, are the Sovteks such a step down in quality to my stcok Svetlana 6550's? I am talking about the price to value ratio here. If my amps used a quad or even an octet, id have no problem with forking out the $$ for Gold Lions. Has anyone given the Sovtek kt88s a shot and if so, were they put back in the box bad? Anyone have suggestions on a lo cost source for kt88 types?
thanks
