The "Plexi 45" is a replica of the
mid 60's JTM 45™.
Unlike the reissue, this amp is hand wired point to point on a vintage
style turret board and is built to the exact specs of the original ( I
do add a 100 pico cap across the normal volume for added clarity).
The output tranny built for me by heyboer with the 6.6k primary plate
load is optimal for the kt-66 power tubes. As in the originals, the
filtering in the first cap is a double 32mf cap and the second is a
double 16mf cap.
This amp uses the early "plexi" tone control values
along with the standard preamp values. You can also order this amp with
the optional negative feedback control adjustable from the stock 27k to
77k (mounted on back of amp). This will give you more or less
power amp gain.
