Hello, I'm selling my BA-3 preamp. Class-A, no-feedback preamp circuit designed by Nelson Pass and released at 2011 Burning Amp festival. I built this as balanced with dual-mono super-regulated power supplies. I built this pre in 2018 for about $1500 (and a bunch of late nights), specifically to drive a pair of diy FirstWatt F4 balanced monoblocks with CLC psu’s I built previously. Killer pairing into horn systems. Clean and quiet with endless headroom. I don’t use it much since moving to a pc-based active crossover system. I’m asking $1400 plus shipping costs and 3% PP fee/or pay as friend. The circuit will accept a single-ended source; simply route the incoming audio ground to pin 1 (and signal to pin 2. The preamp will output balanced regardless of the source. Volume is controlled by a 4-deck, 24-step GoldPoint audio taper attenuator. Resistors are metal film IRC RC55’s: ¼ watt, 0.1% tolerance per Goldpoint’s excellent recommendation. Gain transistors are all matched at normal operating temperatures by Diyaudiostore.com. Each channel has a toroidal power supply with Salas UltraBiB SSLV1.3 regulators. https://www.diyaudio.com/forums/power-supplies/322411-salas-sslv1-3-ultrabib-shunt-regulator.html#post5427621. The result is a really nice sounding preamp. Dead nuts quiet with my La Scalas. For exhaustive details, specs, variations and discussion please see: https://www.diyaudio.com/forums/pass-labs/201281-burning-amp-ba-3b-balanced.html#post2739404 and https://diyaudiostore.com/collections/pre-amplifier/products/burning-amplifier-gain-stage-for-ba-3. I'm in Southern NH USA and will happily meet anyone within 100 miles of Manchester. Otherwise, I can ship double-boxed anywhere at the buyer's expense.

If you're going to the New England Vintage Electronics Expo this Sunday March 1st in Nashua NH, I can hand them over in person.

Horns only! No drivers included! See my other ad selling a pair of Faital HF200 drivers: Taken from a pristine pair of JBL 4670s that have only ever been used for home theater. They were mated to a pair of 2446J drivers, not included in this sale. Horns are super clean with no obvious scratches or other defects. $200/BO and we split shipping.

Purchased new a year ago, these have been driven in a Bi-Amp setup with homebrew Firstwatt F4 balanced monoblocks, 100 Class A watts into 8ohm. These have had an easy life mounted to JBL 2384 horns; never overdriven or abused. They sound fantastic and make a great midrange in a 3 way. I used these on an Eliptrac 400 horn crossed over at 500Hz on a Klipsch La Scala bass bin and a tweeter for >6kHz. Wonderful combo! These are comfortable pulling two-way duty when mated to the right horn, good from ~500hz to 20k with a little EQing. The 2" throat exit is actually a 1.5"->2" removable adapter! This will fit on 1.5" horns and 2" horns! All packed up in their original boxes, will be double boxed and well packed.
