Need Kt88s Genelex? or Shuguang?

Drubage:

What features of the Shuguang 502B did Pacific Valve misrepresent?

Quant100, The pictures posted on their website showed the volume control knob had a blue led on it to indicate it's position. The amplifier I received from them had no led. Shuguang did about 90% of a good job. The amplifier was advertised as having high end audio components. It does, now that I have replaced the cheap coupling caps with polyproplene caps and beefed up the power supply resistors with wirewound non inductive resistors. I was disappointed with Pacific Valve but not with the amp. With the upgrades to the components and tubes the amp performance is well worth the costs.

I am running Audio Valve Challenger Mono Blocks which are auto biasing and can use EL34’s, 6550 or KT88’s. The wattage also changes with the type of output tube; the real negative side of this is that each amp takes (6) SIX tubes! When you are buying Genalex Gold Loin KT88’s x 6 matched prs that is $550 BUCKS- well call me stupid but I dropped it for 12 bad boys and it was well worth it.

My amps came with Electro-Harmonix EL34’s and putting these bad boys in was a huge improvement, starting with just plan more power and with power comes more AC needed to keep the room cool and believe you me it sure gets hotter now; then a much bigger sound stage more controlled deeper bass. The EL34’s have a real luscious mid sound but the KT88’s really rock, especially with Swing Jazz (Big Bad Voodoo Daddy) and Blues (Buddy Guy). Well worth the investment for me, however now I got curious and went and picked up 12 Ruby Tubes (6550’s) and $250 less.

No issues at all so far with my KT88's they have done nothing but performed admirably
