Here's the sixth version of the dirty boots. It's a germanium overdrive based on the first version, but i with a couple extra controls. There's a pre-bass and post-treble tone control combo that's based on similar methods used in many distortion pedals.
I built this version off my own layout a few months back, and I like it quite a lot.
ReplyDeleteHowever, in the Version 6 schematic I was using, Gain is 10kB. Did RnfR change it back from before?
Also, if you use the specified GT313A's, mind the pinout as the saying goes :)
Deleteyea the only datasheet i found was in russian, which i can't read. instead of assuming what the pinout is i went with something more familiar, and a lot of alternate Ge's have as far as pinout.
Deletechecking over the schematic again version 6 does have a 10kB pot, while version 5 has a 25kB. since i made the layout for version 5 first and rearranged it for version 6 i probably forgot to change it in the build notes to a 10kB. the only think i can see happening with a 25kB gain pot vs 10kB gain pot is you'll get more gain out of it.
Hi,
ReplyDeleteIs it possible to add the 5th version's Pre-Gain on the 6th ?
Input to Pre3 and Pre2 to Bass3 is fine ?
So what HFe are we looking for on these transistors?

ReplyDeleteshould be low gain. there wasn't specific range mentioned.
