2015年12月17日 · Does anyone know what transistors were used in the actual SS tonebender mkIII? I'd like to stay as close to the original sound as possible. I've read through several forums and build reports and have seen everything from the russian made gt402V and gt108V to oc81's. 2N404's and AC128's have been listed as being used as well.

3 Perfectly matched, never used, nos Mullard OC81s (2 x OC81s with hfe of 52 & 59, 1 x OC81D with hfe of 128 - British made - the REAL DEAL). This professionally built Tone-bender MK2 circuit also has a bonus mid range switch for more tonal options in different amps. OC81 transistors (REAL ONES) are impossible to find/source anymore.

2021年3月2日 · I’d suggest putting the two withe the lowest hfe up front for Q1 and Q2, and then the highest hfe with moderate leakage in Q3. So maybe number 4 or 8. If you have a breadboard, I would solder some jumper leads on and test a few in Q3 to see what you like.

This listing is for a New Old Stock 3AX31B Blue Dot PNP Germanium audio transistor suitable for use in Tonebender style guitar fuzz boxes or as a replacement transistor in the preamplifier stages of many 1960's transistor radios, record players and amplifiers, where it is similar to the OC71, OC75, OC81D, AC125, AC126 and AC128 (when used within...

2010年5月4日 · I see that OC81D is the recommended tranny for this circuit HFE at 70 70 100 for q1-q3. But, the OC81D does not seem to have that high of gain.....according to datasheets..... And I see theres a bunch of people that have built them using …
