DC B1 pre-amp with phono stage

[disarmamant]

Too bad that I haven't been able to make my Benz Micro Gullwing SLR sing with my Partridge 977 SUT - also one of yours, by the way. All the mm-stages that I have used with that combo has sounded off and strangely bland (EAR 802/Croft Riia R/Pass B1). Did you ever build a Pass B4 buffer, by the way?

I have not built the B4 buffer, is that a Nelson Pass design? The Pass Labs B4 is an active cross over isn’t it?

Sorry to hear that your Benz does not sound right through the Partridge 977’s. How are you using the transformers? Are you trying to load the primary or secondary windings to match the cartridge?

Martin. Let me PM you about the Partridge.
You build some stunning kit! I only wish I had a DIY skill set.

Re: B4 pre.

I stumbled over a post on PFM comparing a B4 build with the Pass B1 pre. Assumed that it also was a Pass build but I think I must have been wrong. The B4 pre in question is indeed Piglet's Dad's build on PFM. Just found the relevant threads.

Just answered your PM by the way.
