Default F/s Aksa 100n

AKSA 100W power amp with Nirvana upgrade (not N+) for sale in Leeds, UK.

Built on Version 1.74 boards (the boards have minor modifications to bring them up to the designer's later specification). I think this is the optimum AKSA and chose not to implement the N+ upgrades because I did not like the "black gate sound" when tried on my AKSA 55.

The amp is dual mono, using 2 X Nuvotem 300VA transformers (Part Number 92541) 35-0-35V with genuine 240V primaries (these toroids were custom wound for me so you may not find them in Novotem's product list), zero mechanical hum, low flux (for audio).

The case is custom made from 3mm aluminium (no steel - except for the screws) with black powder coated top, bottom and rear panels. The front is 3mm thick black anodised aluminium. The cosmetic finish is generally good with but with some small marks and a couple of hairline scratches on the top of the case. Pictures, internal and external, are available if you send me a PM

Overall dimensions: 445mm W X 306mm D X 87mm H (+ 3 or 4mm for the feet and
20mm for rear panel connectors). All screws are black countersunk or button-head hex screws.


Sound quality - I think you all know!


Price 450.

Soldering detail showing emitter degeneration resistors added to bring it up to later spec.

Also showing o/p inductor damping resistor(s) (Hugh later implemented my suggestion here, on all his boards).
