Looking for a new Amp or Preamp? If you're after tubes, post over here.

Manley Lab Series 75+75

Does anyone have any information on this amp, besides what is posted at manley.com? Any reviews? I can't really find anything out about this amp. I did download the manual...

I know there was also a VTL Stereo 75; is this the same amp? I see a variety of tubes, from 6550's to Ei KT-90's. I see in the manual that it uses 'special' Russian 6550A's -- what was so special? Did this amp have a particularly high plate voltage or something? I see these pictured with EI KT90's -- does this change the bias setting and to what?

Can this amp also be changed to triode mode? Anyone know anything about stability with Quad ESL's (57's)?

Thanks to anyone with any information!
