so the 700s
power supply voltages are exactly the same as the 717 and 727
from the transformer yellow,green,yellow go to full wave bridge rectified and regulated to +/-15
blue black blue (the filament supplies on the 700t) rectified and added to Vh- to make the - boost supply
white red and brown orange are the 2 high voltage windings full wave rectified into CRC making +/-350
output boards identical to the t8000 each board has 3 x 2sc6127 and 1 resistor
vas boards have 4 x 2sc6127 (2 x Darlington pair) and 4 x 150k/2W current source (on main board)
vas is driven from dual low voltage n-channel jfet. (red heat shrink) (previously dual npn transistors)
front end identical to 717/727 with dual n-channel jfet
so about 99% identical to srm717 with non-obsolete parts and change of vas stage driver from bipolar to jfet
on the D50 the front end jfet is known to be sourced by linear systems. So likely the k170 are also sourced by linear systems.
so the 700T
absolutely identical in every way to the srm-007t (and srm-t1 etc) with 2 x 6sn7 replacing 4 x 6cg7
plenty of room for replacement constant current sources to replace the mills load resistors
both are priced the same, between $2895 and $2995
