Woohoo! You've just reignited my faith in bodgering. :tu: :tu: :tu:

Cheers J M I was just a bit cranky after reading that thread. About the DoubleD, would it be possible to simply link the outgoing signal straight into the input of a power amp circuit via a vol pot ( like my Vellemans ), or would it need some extra bodgering.

Jim.

Looked at the datasheets for the 2050, and I must admit a lot of it went over my head. I suppose all that I'm doing is copying the schematics of circuits when building and not really learning anything exept soldering skills. I've just read a thread on this site about valve versus tube sound, and I'm sure the guy who started it has now got a Phd in electronics, it really was that complicated.
Do I really need to be that knowlegable to build a decent amp or would I be better off just building a pedal to get the sound I want.

p.s. At the time I joined this site, I had been given a Fender Frontman 15G that wasn't working and was told "if you can fix it, it's yours". It got sent for repairs, (hairline crack on pcb apparently, and he also changed one chip) and after trying it out at home have decided that the drive channel is too fizzy and that's why I asked about the DoubleD circuit as a pre amp.

Pissed off now, going to play with some Lego. I understand that.  

Holy cahones BatBloke !!!. That's sweet. Thing is how would you bridge these in a circuit bearing in mind I'm still a thicko at at this stuff. :lmao:

Early last year I was working at a local school that was throwing some stuff out and I came across a large cassette player / recorder that was designed for use in language classes. I tried it out as a guitar amp but the hiss was terrible, so I thought I'd keep it for spares. Inside I have found two TDA 2040 op amps and a 9514 BD 438 transistor. Could I use any of these to create a worthwhile power amp for the DoubleD pedal / preamp. If so, what power could I expect through various impedancies.

Thanks

Jim.

Nice link joe. It always amazes me seeing electronic circuits, has done since I was a kid. I honestly don't know why I've started to tinker with them now, must be a male menopause thing. Anyhoo, thanks for the advice everyone, hope to chat again soon. :tu: :tu: :tu:

Cool. Thanks for the replies. Are these amps " clean " or will they produce some distortion.

Hello one and all. As you can no doubt see, this is my first foray to this forum, and I shall ask, as I see fit, to ask stupid questions and generally seem a bit of a tit. Anyway, my knowledge of electronics is minimal but as an electrician I do have some idea of what's going on, and with the help of DIYAudioprojects.com, built a small stereo Mp3 amp with two Velleman K8066 3W kits. It's not pretty but it works.
My main passion though is the guitar, and as a budding bodger, have looked around the web and came across Runoffgroove's DoubleD effects pedal which sounds gorgeous and would make an ideal pre amp, but to be made into a head unit or combo would need a power amp.
Now, the more alert ones amongst you will know what's coming next so i won't keep you in suspense, what would be a simple power amp to construct for a beginner( different wattages, speaker impedancies and the like ).
