HI
Thanks!
The odometer is "hour" meter. You can see how long the tubes have been in use. Powertrafo is the Hammond W1650. The toroid mainstrafo is custom made.
Sound is a subjective matter. I wish that I have had that amp much earlier. To me it sounds really good and unique.
some specs:
tubes:12DW7,12AX7,12AX7, 12BH7 and six 6550
RMS power: enough
(c.300W 4Ω or 8Ω load)
Anode voltage: 685V
Weight: 30kg (c.60 lbs?)
dimensions: 32cmx35cmx54cm
Fan cooling, 1,6mm fiberglass eylet circuitboards, Teflon wire, ceramic sockets, metalfilm resistors, polypropylene signal caps, Alpha pots,bias control points "outside" the chassis...
The circuit is my version of A. SVT circuit. The input circuit is the same, as is the preamps voltage (300V). The tone controls -baxandall, ultra low, ultra high, are the same as original. Mid control is abit simplified (like V9 pre). It still has that toroid coil (self made) LCR-circuit.
The phase inverter is normal so called "long tail pair" unit (As found in many 7ender amps). Not concertina as in original. From that point the poweramp is the same as original.
