Anyone got any experience using the (Tube Amp Doctor) TAD KT88-STR, any comments on how thy sound, consistency, or reliability, would be appreciated?
Its a Chinese (Shuguang) made valve.
Not a lot of info out there, Hot Rox UK sells them and rates them for audio, being their favourite in the KT88/6550 group. Preferring them to the Gold Lion which they also keep.
I'm using a Graaf 5050 amp with pairs of KT88 in push pull and looking to replace the 4 budget items that came with it (VT Gold Class).
