ToT + Resonance

[sinusoids]

Thanks for calling my attn to this kit - I had to look it up to what you were referring to and had not looked at the extensive kit catalog in way too long. One of the QRKs could be used to switch channels as well. Transistors in eyelet cards gets tight. Maybe a 7912 to supply the QRK. I had planned to use a vector card for the switching stuff.
What amps did you add these to? I decided to build ToT due to the LPSP because I didn't want to commit to the Standard amp build having never heard the this preamp. Kept putting it off. and off.
