I recently purchased a very nice quality passive pre from a member of this parish. Whilst this was a nice sounding bit of kit, I wasn't so keen on the sound of the SMD metal films in the DACT pot, to my ears giving a harsh sound. Nick had kindly sent me a pair of Dave Slagle TVC transformers to try, so I thought I'd fit them to this pre. I wanted to do this in such a way that it could be returned to original with the minimum of fuss.
Here's the pre-

Bought some U section ally to mount the transformers on-

How does it sound? Dunno, just finished late last night, might get it plumbed in this evening if I get a chance.
