Bartolini TBIBT 2 band/active buffer preamp £35 posted - *SOLD* £35 Co.Down

[Gareth Hughes]

Hi all - here is an old Bartolini TBIBT preamp. Bought way back in 1999, maybe 1998. I've just never been an active guy so this came out fairly quickly and has sat in a drawer since. I took a notion a while ago to try it out again but I think the blend pot is the wrong value as the both-pickups blended signal seems to drop in volume more that I think it should. So my caveat is that it's working fine if you know how to wire these things up, which I don't. £35 posted. 

 

Here's the wiring diagram:

What is the blend pot value used in the picture? I think these blends were meant to be 25k. Could be interested.

I don't know - there's no value marking on the bottom. These are the only markings on the case:

The schematic in the link says the blend is 50K.
