Looking to sell an all tube preamp built by Blair Chapman, who is a designer based in Dallas.
Preamp details:
- GE 8CG7 based tube preamp with Toroidal transformer.
- 3 inputs, and 2 outputs.
- 100k Alps blue pot (Mouser part # 688-RK27112A00AK)
- Jantzen caps
- Upgraded Aluminum Knobs from PE
- Mahogany Front and Sides, with study metal top plate
- Detachable IEC power cable.
















I have used this with my powered monitors with great success. The second output was going to my subwoofer. I requested Blair to not expose the tubes as i've small curious kids. The end result is a great little preamp that can fit on any desk, and sounds great with zero hiss whatsoever.

Could you please take a photo of the internals?
Chapman apparently had more that one version of this preamp and yours is certainly different than his standard layout.
TIA

Will do. I've never opened the preamp up, but will take some pics later today.

Bump for what I’m sure is a nice preamp.  I just sold my Blair-built SRPP design preamp (only because I decided to build my own) and it was a really nice piece.  I wouldn’t hesitate to buy another one.

Thanks for the bump!
Yes, Blair has always been a standup guy, willing to answer any question, and always stands behind his product.
