For Sale DIY Neurochrome Modulus-86 R2.4 power amplifier

Things you have for sale.
SOLD

Asking $600 $500 / best offer, plus Continental USA ground shipping



For sale is a DIY build of the Neurochrome Modulus-86. This is using the previous version of the signal boards R2.4. It does use the LM3886 chip to provide very low distortion power of 40 Watts into 8 ohms and 70 Watts into 4 ohms. It has about 100 hours of worry free use so far. I was going to use this in an active crossover speaker project but have changed plans. I am keeping the brother to this amp for day to day listening.

This is a revealing amp, producing what the upstream components give it without added distortion or coloration. Solid bass and extended highs as you would expect.

This is a balanced circuit amplifier and has XLR input jacks only. You can use rca input easily by adding a male xlr to rca adapter to the back of the amp. I WILL include a pair of the adapters with the sale.

The background noise is essentially not there on my 97dB sensitive speakers.

Input sensitivity is 1.8 V to full power.

The power supply uses an Antek transformer into the Neurochrome Power-86 R1.2 board. The mains fuse is inside the amp, and I use the lowest recommended amperage fuse, 5A slo-blo and have never had turn on surge or other variations blow a fuse.

The amp is in a Modushop 2U tall x 300mm deep steel and aluminum chassis. The heatsinks barely warm up with normal listening. The front panel is 10mm thick, with a red on status LED.

There are no surge suppression or speaker out protection, but I have never needed it with these level Neurochrome products.

Weight of the amp is 22 pounds, and it will ship in a 20 x 20 x 12 inch box to the Continental USA only.
