P.S. Mr Fahey- I have just been reading some of your posts on the topic heading "making reverb".

Crikey!

Yeah I know. It is pretty twisted. It's an old english pastime, having a good moan.

I have got the "power" amp built, now I'm pondering the preamp- any good ideas? I have had good results with the Fetzer valve/Tilman FET circuits. I don't need massive amounts of gain. I like a juicy but clean sound, although I am partial to the sort of Jack White/garage fuzz/distortion too- channel switching maybe?

Also, any experience of the Belton digilog reverb? Looks quite tempting.

So I had my shed time. Now I have another piece of vero board scrap- the damn thing is driving me crazy.

I have a week off work next week so I'll get some shed time. I'll let you know how it goes.

Cheers guys.

I have some pictures here...



It started out as a one knob battery powered practise amp based on a circuit like the one shown here:

You know how it is though, the temptation to add a bit here and there...

I got the reverb tank of ebay, which is ok but it needs more than 9 volts to get going, hence the need to use a mains transformer supply (did I mention that?!)

The tremelo circuit was improvised, based on the Rickenbacker TR7 and was sounding quite lush when it was working.

Thanks for the kind words, I just need a bit of a push to get into this again.

Hi,

please help. I am an amp building enthusiast. Last year I started a project which was a battery powered transistor amp on the lines of a sixties radio circuit. 4 transistors, 2 transformers, a nine volt battery and an assortment of resistors and caps. Simple.

The circuit developed as a prototype on veroboard and sounded good, better than I had imagined it might and quite loud, at least loud enough for a practise amp which was the intention.

So far so good. But then it kind of grew. In my enthusiasm I added tremelo and reverb and even a second drive channel. Little by little my simple amp has turned into a monster, a mess of veroboard and wires and still as yet unfinished.

I have built 4 "prototypes". I can hear the potential. The little thing sounds good. But I can't get the construction, the assembly right, consistent and reliable. I think I need to produce a pcb.....

Trouble is at this stage, my enthusiasm is spent. I've turned to the forum for hoping for some words of encouragement.
