well i just finished completely giong over a ts 5 i had aquired on the

to get the ts 5 to react more like a 9 …
in addition to changing the op amp to a better one
the key is altering the feedback loops around the op amp

on one side of the op amp you have the clip circuit

i changed the .047 cap and 4.7 k resistor
to .1 mfd and 2k

on the other side of the op amp … driving the level control
i changesd the feedback 1 k resistor to 1.5 k

these two small mods increase the output distortion and compression of
the 5 to levels more in line with the ts 9

i don’t know why these adjustments are needed as my ts 5 appeared to be
schematically identical to a ts 9 but after many parts swaps and much
hair pulling not to mention crispy burnt
long haired rocker with a soldering iron smell
my ts 5 sounds cooler than my ts 9

most excellent …
i must now retire and practice my stairway to heaven
for my next visit to the local guitar store

special thanks to rg keen for his inspiration
