Opamps are in a dual 8 pin dip, 4558. All transistors ZSC1 815. All diodes silicon signal diodes, 111914 or similar.
np* = nonp olorized resistors denoted by * marked as 1M on original might be 22k and those marked as 56K
might be10k. crfi and cr2 are a special cap and resistor in parallel, the cap is 51p the resistor is 56k.

To converT from a TS-Q To TS-BOB:

- change To 100 ohms
change To 10k ohms

Q1 and Q2 may be any low noise NPN TransisTors such

as The 2N5088, MP56521, MPSAIB, or similar

Recenr uniTs have conTained The TA75558 dual opamp
which is noT The besT choice for This circuiT. Upgrade The
1C1 To an RC4559, LM833, TL072, OP227 or similar
improved chips for befier performance.

The TanTalum 0.22uF cap on The Tone conrrol can

be changed To a poly film Type for befier response.
Also, iT may be lowered To 0.1uF To open The range.
