I know that interest checks are not allowed within the For Sale section, however, as this is the DIY section I thought it may be ok to ask the question!?

Mods, if it is not allowed, please remove the post and I will consider my self reprimanded!

I have a Pass DIY A40 power amplifier that was intended for repair/upgrade and is partly finished. However, this was my first DIY project and before finishing the amp I decided to use it as guide to build a new A40 in two enclosures - a-la monoblocks.

As such, I have the vast majority of parts needed to complete the new project but have run out of steam and have decided that it may be best to pass the gauntlet to someone with the drive and knowledge to complete the project.

Ideally, I would like to sell as a job lot, either for someone to finish or maybe salavage parts. The parts include:-

The original A40 project amp - This is a beast of an amplifier and the enclosure and heatsink alone must be worth £200 - £300. The amp will come with all the original parts and components.

2 new aluminium enclosures - These cost nearly £150 with shipping and import charges and are very good quality

2 stereo sets of professionally made A40 PCB's (4 boards total) - 2 boards are required for an amplifier (i.e. a stereo pair), so there are 2 boards for the new amps and a spare set. These cost around £50 imported from America

5 x New Epcos 22,000uf 63v 105 degrees power capacitors - 4 capacitors are required for the new amplifiers so there is one spare. These cost around £125 with shipping etc.

4 x New Audio Note Keinsai 470uf 25v signal capacitor - These cost around £30

In addition to the above, for the new amplifiers I have all other PCB components as per the published parts list (attached), including the output darlington transistors and the mounting hardware. These parts have been sourced from various places all over the world over many weeks, easilly costing £200 + and most components are supplied in pack sizes of 20+ for easy matching.

In order to complete the new amplifiers, the only other parts required are heatsinks, transformers, your choice of speaker binding posts, RCA connectors and a couple of fuse holders.

I am aware that I won't get back what I have spent, as is usually the case, but I would be looking to acheive £500 as a job lot and could potentially ship it at cost.

Would there be any interetst from the DIY community??
