Just a little side note:
tremolo's transistors are not the same as in schematic:
BC109 is the current mirror
LFO's is a BC114
and the variable resistor is a BC172
Depth pot, is somewhat funky:
it measures 250K despite it's marked as 0.1M on case (100K on schem.)
I have a drawer full with old recovered parts I collected in years...
well I have 5 LESA pots (the same mounted here) marked 0.1M and all of them measure 220K-275K

thanx alot for posting that!
just wanted to check a couple simple things about the schematic before I attempt it...
the "," 's are "." 's here in the US, so all the 2,2K's and 3,3K's and 3,9k's and 8,2k's are 2.2K, 3.3k, 3.9K , 8.2k and the 0,1M bottom right is .1M = 100K ?
...and what are "k" and "kp" capacitors?

well.. it is a fuzz...Bernardduur wrote:Looks really cool! How's it sounds?
I'm not so deep into this..., but it is smooth, different from schmitt trigger fuzz...
It sounds smooth and old to my ears
I should try different trimmer settings 'cause those collector's 4V marked on schematic looks like a rounded value, considering the time technology involved...
Tremolo is more effective with fuzz on.

They used elder markings k and kp instead of nF.LucifersTrip wrote:...and what are "k" and "kp" capacitors?
Electros are 5uF/6V and 5uF/25V (instead of 12V)

Cool, where do you guys find all these old stompboxes?, I've seen some mentioned in the Vintage Stompbox Corner that I've never even heard of before.....

you won't believe it was laying in a barn...
In Italy, elder musicians keep their old gear in the strangest places...
I found this old beauty in a similar manner...
