    Replaced the chip with a J4558 and switched two resistors in my TS9 today. Plus the 3pdt and brighter LED and I've got a sweet TB TS808.

    I noticed something funny, when I removed the old chip, a (TA?)75558P, underneath it printed on the board it said "4558". Do all Ts9's have that?

    Can you hear a difference now, after the mods? I once had the TS808 circuit on my breadboard, and swapping out those two resistors to make it a TS9 made absolutely no difference to my ears. Nothing I couldn't replicate with a tweak of the tone knob, anyway.

    Not sure yet, I'm in class so unfortunately haven't had the chance to crank her up. Later today ill let you know.

    Yesterday my first reactions when I tested it was that it was a little brighter, I had to roll the tone knob back a little bit. That's about it.

    My TS9 said 4558 when I replaced the 75558P chip.

    Love the mod, subtle differences and with the resistors replaced, you have more low frequencies coming through now.

    I've built tons of these, no audible difference to my ears.

    I have done the 808 mods to a few also. I don't here much from resistor swap but I can hear the difference in the chip swap.
    I haven't done a TB mod to a ts9 yet. It is the only buffer on my board at the moment and I figured it was a good idea to keep it in the chain.
    Once I finish my Klone build I will probably TB the ts9/808.

    Btw chip swap is subtle, definitely noticeable...biggest difference is in diode swapping. Ive swapped out 1n914s for germanium, LEDs, 1n4001s just figure out what I liked best. But that's a whole different story...

    TB was a fun mod for me. It was the first one I've done completely without my dads help, haha. Definitely add pull down resistors, it'll pop a little.
