Looks less blingy now it's boxed up and only the top of the valves show :)
Thansk for posting the mods and schematics Alan. Is that silly led get-at-able with a sharpie? if it is i may well make like a rolling stone and paint it black. :)
Tell us how it sounds on your CD player Alan.Quote:

I've just looked at the ebay listing...
HOW MUCH!!!!
A couple of valve bases with p+p would cost more than that from a UK supplier! I'm gobsmacked.
I was going to say that I didn't really see the point of this thread. That type of PCB construction is great for getting a circuit as compact as possible and it keeps production costs down for commercial products, but if you start modding the circuit or the board it loses those advantages and you might as well have hard-wired the circuit from scratch.
However, having seen the price I can see the attraction. How can they make any profit on that?
Thats what you get for making parts in huge bulk and a cheap labour force. Buying these things, even to strip for parts is a decent way to run a build business
Personally, I am very grateful they make them so cheap as it's gonna save me a lot of money to try something new. Alan knows his stuff so I'm very grateful I live so close to him too lol.

That was it for me too, £15 ish with the power supply ive ordered? Why the heck not. I've never heard Valves at all in audio, only guitar amps, so it seems a great way to dip a toe in.
I just ordered the boards but I already have all of the components. I'm not sure if I have those particular transistors, but I'm sure I have some that will work. I've probably got a few weeks to find some if I don't before those things make it here from China.

Those transistors haven't got much voltage across them and aren't carrying a lot of current so almost anything will do as an alternative.
