Tidy piece of work Alan, I take it it's a naim clone.
Have you had the chance to listen to it yet?
Regards
Greg
I have some of these boards......somewhere:scratch:
I was going to pair them with a B4 that I built, but had a problem with it and so got shelved. Dodgy ebay parts me thinks.
Nice build.

Yes Ive been running this amp for about 9 months now and its excellent a great all rounder really
As you say its actualy a Naim Nap / Avondale NCC 200 plus a few Acoustica tweeks hybrid but it also has a seperate front end power supply which makes all the difference :).
Mine runs on 53v rails for the output and 56V for the Front end so there is approx 100W into 8 ohms.
Puffin I am also using this amp with a B4 and they are a great combination so try and make time to build your Hackernap power amp.

apart from my RCM which i just finished, this is all I still have and use, a Heathkit aj-1214 am-fm tuner I built in about 1978/79

A few years ago I made some LM3875 monoblocks point to point with a regulated PS (see Decibel Dungeon) for details. Nice amps and better than the LM3886's IMO. Nice build.
Few pictures of TDA7293 MOSFET based 2.1 integrated amp project.

I was looking around for quite some time trying to find a simple buffer to drive my high gain power amplifier. Too much gain is a curse that afflicts many systems. It's always seemed nuts to me to throw away most of the signal as it comes in then amplify it again, which is what a normal preamp does most of the time.
The B1 starts with the premise that there is enough gain already and that the only tasks of a preamp are switching, impedance matching and attenuation (not amplification), with attention paid to maintaining the musical integrity of the signal (including nuance & timing) that can get lost on the way through.
This is my first put together Pass B1 buffer preamp. Cabinet is an all-metal case with 8mm anodized alloy faceplate(final).
Few pics of the build.

pics of my finished B1 Preamp, all wired up and ready for an audition. The source is a Rega Jupiter CDP.
Overall, I am super pleased with this preamp as you can probably tell. I would advise anyone to give it a try. Very simple to build, it doesn't need to be expensive, and you may hear a lot of what your current preamp is not telling you.

Hi all DIYers,
Building a 300 watt Hi-fi power amp, which we designed and prototyped few years ago.
Please follow the links for details.

PCBs have been fabricated and gathering all components on hand.
Few pictures of the same.
