Hi Folks, I"m new here and this is my first Post ...But I am not that new to DIY Electronics as I have built a couple Guitar amps useing IC"s and have built many Mic preamps and Stompboxes and a few Gainclones other music related audio curcuits Pluss my Guitar is a heavilly Modified Ephiphone......
The Guitar amp I use now is a 50w one Based on a LM3886 Power amp IC and a discrete J-fet Preamp stage with tone controlls and 2 Different Overdrive stages which are user selectable....This is a fairly Loud and extremely heavey sounding amp but I now want something with a bit more Power and with a cleaner output ,Something that I can play shows with as my 50w one is loud enough but at that Volume it is hard to get a clean Tone out of it .......
I happen to have quite a few Transistors that would be suitable as output stages and have a couple good Power Transformers (30v,0v,30v-200vA) that should be adequate for building an amp in the 75w range and I have lots of Parts but I am haveing trouble finding a suitable Schematic/Project that would utilize the Parts I have available so I am here to ask you good Folks if you could maybe point me in the right Direction.......
Here are some of the Transistors I have:
MJ11016/MJ11015 30A 120v 200w To-3 Darlingtons
MJE3055/MJE2955 70v 10A To-220
Tip31C/32C 100v 5A To-220
Tip41C/42C 100v 7A? To-220
BD139 80V 1.5A SOT-32
BC550C/560C 50V 100mA T0-92
2N4401/4403 40v 600ma T0-92
2N3904/3906 T0-92
2N2222A T0-92
IRF630 200v 9A N CH-Mosfet T0-220
RFP8P08 80v 8A P-Ch Mosfet To-220
And I have some Various other Small signal Transistors and some J-fets and all the Caps and resistors and PCB material I need, or at least for the most Part......
So if someone knows of a Guitar/Bass amp project that will utilize the Parts I have or even a Power amp stage that would be awesome.......
Thanx a Lot.....
Cheers
