Bellari RP-533
# 23734
Heavily modified by Vince. 7 new switches, overdrive control, combo mic pre/comp/eq with many added features. Low noise high gain tube modification. 2 Band Bass/Treble. Front panel paid gain/phase switch. Tape saturation control. Smooth fast compression switch. High gain / bright switch. Power supply ground mod. Transformer EQ optical mod. This is the cats meow! Call for details 617-926-8020. Top flight cosmetic condition #8 with just a tiny bit of rack rash. Some additional information customers have asked about: This unit is 90% all tube, the op amps are for RMS, DC control, balanced out not audio! What I do is make the circuits have more head room less noise better tube character and more correct RMS detector tracking. As you may have noticed the output circuit clips badly and is nowhere close to semi-pro level. It's a wrongly done balanced line op amp stage. Also the compressor threshold and ratio controls are too sensitive, as such the unit can go into a strange and not very likable distortion if pushed. There is some good basic design circuits in this, but just not enough. My mods are not about installing fancy parts it's about improved circuit performance

Behringer Truth B2031P (pair)
# 56025
For sale Audio Pro Rev. 4/5 Modified passive version. New. 2 way passive monitor speaker (pair). Audio Pro modified. Rev 4 Design. Custom cabinet damping. Model 2031A are amplified speakers. I suggested 2031 passive design, and to use any good 40-100 Watt amplifier. Check out the Behringer website for a picture. A modified set is $448. We modify the 2031 to be a near field monitor where midrange tone is "warmer" or slightly receded image by a 3db through about at octave between 800 - 2000 H3. A far field monitor version is slightly brighter or stronger midrange and designed to listen at 4 to 8 feet distance. Basically flat response is perceived at that range. Near field version is for 2 to 5 feet away listening, and indeed most BSEE acousticians agree that a near field should be dipped in midrange. In both cases, the modification consists of improved multi section crossover (it presently has a very simple 4-part crossover) as well. We install a dampening blanket between the internal chambers, dampen tune one of the port slots and finally apply soft felt clone dampeners to improve midrange level and tonal match to crossover. The cabinet is now tuned to reproduce 40 Hz powerful and clean. The speakers are very heavy design with cast frame woofer, using high density MDF cabinet, very well done. No grill cloth is included by design. Shipping can be $38 or so to get them to you.
