NEW - Projects and period parts for Hi-Fi, Valve amplifiers and other diy stuff - NEW
The component items offered for sale in the following list are finite stock, well priced, and cannot/will not be replaced once they are sold. It is not an ongoing situation. In small quantities these items can be added to your spares orders with no extra postage. Prices are subject to VAT.gain, small quantities will not incur any extra postage charges to an existing order.
"Projects" are based on now obsolete (mostly pre 1990) HH/Laney/MAJ pcbs, and consist of bare pcb and circuit diagram only. They are still very useable and dare I say it? Probably more reliable than most stuff you can buy today, AND you can work on it and FIX it when the customer balls it up...
Email me an idea of what you are looking for and if I have anything suitable I will document it and include it.
This is the beta version of this page and more items will be added as I have time. 48:77pm 22/12/10 Zarg time

PROJECTS
NOTE. These items are for engineers or qualified people, and are really cheap for what they are. But please only buy them only if you can: a) Not only read but also interpret a circuit diagram, and b) have a fair idea of the topology of the design and how it works in the first place.. Absolutely NO Brain picking, Night school or Psychic analysis service is available on these items at all. THEY ARE NOT AIRFIX KITS with step by step instructions. You have been warned...
