of pre and power amps.BTA the FVP built for me in a QUAD 22 box plus remote PSU by Allen Wright's business when still here, rapidly (<2 yrs) developed problems. AWE got a Chapman multi-band mono valve tuner, two QUAD IIs, and a LEAK St60 on loan, to tell me what he thought of it.
(When I finally dragged the 60 away from Joe Rasmussen I swapped it for two LEAK St20s which are now Once Were's to my delight. ?? See Reviews here. They are now in the same state. ? Four 470uf 400V dark-brown Nichicons two of in each case in series? and the last two bypassed. )
The pre-amp is still similar in design to an FVP. But uses just two Sovtek 12AX7s in the RIAA phono* stage. The line input and extra gain* stage is a 12AT7,
and the output is a 12AU7 in CF,
instead of a 12AX7 in CF .....
.... which is an idea you'd have to worry about - in an AWE's fame context - eh?
Perhaps he skimped on the PSU, eh. Heaven forbid! ;-)
