Here's a Tone Bender Mk. II variation from DAM for Fuzz Friday. Originals use PNP transistors are are positive ground effects, but it could be built with NPN transistors as well (negative ground). This varies from a Mk. II in that there is an added tone control (Flesh), and the fuzz control is a fixed resistor. Schematic here. The perf side of the layout reflects the positive ground orientation of components, and the pcb side the negative ground orientation.
I used soviet germanium MP38 transistors, & 8.2k resistor you have to change for god loudness, resistor 1 k i took potenciometr.Great sound.Thank you very much!

ReplyDeleteSorry to be needy.
It's there now. Sorry, I must have forgotten to upload it.
DeleteSome hfe specification?
ReplyDeleteUse a ToneBender set! 60. 80 100. Around there! Test a bunch out.
DeleteIs the 8.2k doing the biasing?
ReplyDeleteYes, the 8.2k resistor on the far right is biasing Q3
DeleteVerified ! Good job.
ReplyDeleteGreating from France
Thanks for verifying!
