My kit arrived yesterday. Many thanks Carl! Your efforts on this project are not going unappreciated.

I will likely not get a chance to work on this project until the xmas break, but will be looking at this thread closely to see the early progress from others.

THANKS AGAIN!

PS. any USA folk got any great ideas for the enclosure?

Or anyone?

Or anyone?

Of course, anyone should comment. I just mentioned USA since there was some previous discussion about nice enclosures, but based in europe which might end up being expensive for us in the USA.

Q1 -BC560CTACT-ND for the power supply is out of stock at mouser and digikey. are there any other transistors that could be subbed?

BC 557, 558, 559 and 560 look to be the same PNP but sorted for voltage and gain. I would think any of them would work equally well in this circuit. Mouser shows that they have a bazillion of the BC559CTA parts in stock.

 

[mik000000]

thanks Carl. i went with BC557. the specs look identical to BC560.
it is digikey# BC557ATACT-ND


parts ordered. more waiting.....

Enclosures in the UK

Hi,
The enclosure is the part that causes me the greatest trouble. Recently I have been gutting dead audio equipment and shoehorning my boards and PS into them. It has worked out well but it will not for the preamp because of the specific location of the pots and other pcb-mounted devices.
Anyway, I have collected a set of websites of companies that look like they could supply what I need. Apart from Ghentaudio, I have not dealt with any of them.. but they look more than capable. It will all come down to how much you want to spend. My list is:

i like your recycling option. my only observation is there is nothing to stop us from wiring the pots instead of mounting direct to the board.
