Rare find Blowtorch Audio Preamp

Went to one of my local dealers today to buy some used records and on the used audio shelf was a Blowtorch Audio Preamp in excellent condition. This was built by 3 people back around 1997 by John Curl, Carl Thompson and Bob Crump. John designed the circuit and power supply. Carl Thompson created the optimal board and Bob Crump selected the parts. The Preamp and power supply were housed in billets os Aero-Space grade aluminum. Some build features include teflon insulated silver wire. A fully symmetrical circuit. Gold plated circuit boards. Toshiba NOS Jefets and Hitachi NOS Mosfets. It's all hand soldered w/silver solder.. It has 2 separate volume controls and a phase reversal switch. John Curl called this preamp his finest effort. New in 1997 it was $20,000. The production number on the unit was 0004. Dopey me I forgot to ask the price. Very impressive and rare.

in October of 2003 Bob Crump was doing a ’tour’ with the Blow Torch preamp + Vendetta phono stage and visited me in my old room. he had been traveling demo’ing to various people. he left the Blow Torch with me for a couple of days and i compared it to my Placette passive in my system. in my particular system at that time i thought that the Blow Torch was really great sounding and very dynamic, and maybe the Placette (passive volume control + custom Jena Labs passive switchbox) was a bit more out of the way of the music. so i did not pull the trigger to get the Blow Torch. the Vendetta was also very good but a ’push’ with my Lamm LP2 phono i had then.

Bob was a real larger than life character (in the best sense) and sadly passed away a few years later.
