Okay so I'll leave the tone mender Idea and maybe later add a tone controls to the clean channel : ). Thanks for help.


I looked for the zenner regulated supply but haven't found any thing that tells me how to design it or how to make it -. Only what it does.

NVM I think I still will go with tone mender. My last question is how to get a 9v- from the same supply that goes to the power amp? Oh and how can I built a regular channel switch+foot switch that I will connect to a jack (but at least for this project it is optional)

Oh ok. I think I'll drop this idea.

Yes. But this sould be not so hard to build if you have no tools. Also it would weight less

Hay, I had an idea instead of building a cab form wood I can use old computer case like this as a 1x12 cab (after I remove all the stuff from there and try to close the holes at the side of it.


Do you thing that will work?

Fine I'll go with the 2x6v minwa. Is it the power supply or do I need anything else? Also you haven't answered me if the tone mender is a good clean preamp and do the amp need cooling (another heat sinks or whose fans like in computer power supply (I use one for a box).

I have an MG15 and I pretty like it's clean preamp. I don't want to use it only the speaker. I have a store (+in the web site there is no products) but the Power Supply are pretty harshy (in FX pedal some power supplies work quieter then other so I think in the amp is the same).

What about the tone mender, the switching and cooling for the whole amp (is it needed)?

Here is links to the store http://www.talmir.co.il/main_category.asp?c_id=427

Okay I'll build this preamp (the small one) but do I need a heat sink for the preamp, and how much ohm does is produces (can I use it with the speaker of an mg15cd). Also is the tone mender a good preamp? The channel switching will be a 3pdt and two will switch between the input and output of the preamps and the third one will select to which preamp the power will go. Do you know how can I add a footswitch (and the regular switch on the amp)?
Oh also the kit needs 15volt not 12. Oh and where can I get a 12V power supply which will work with 220v (I can't find any good one in Israel)

I looked for lm3886 and tda7294 kits and all are 80w plus. I want it too be at least 15watt so I think I'll go with higher volt power supply (but I have no ideas how to build it and how to adjust it to 220 volt which we use in Israel. I understand in America you use less). For preamp I will go with shredmaster and tone mender and maybe later I'll add an fx loop. Still I don't know which power amp to build and what to do with the power supply. I prefer cheap stuff cause I am a teen and I don't have a lot of money (But lots of resistors and capatitors).

To get 18volt biopolar power supply can I first use this to get form 9v a 18v http://www.geofex.com/circuits/+9_to_33.htm
and then use this to make it bipolar http://gaussmarkov.net/wordpress/circuits/bipolar-9v-power-supply/?

Okay I chose to use a shred master as a dist channel and I need to find a clean channel (I though about the tonemender but some say it pretty sucks). Also I need ideas for power amps (If it is not kit it will be better cause the kits are expensive).

Well the possibilities suck. The components aren't really great quality and there no different types (there is only ceramic resistors) and they are pretty expensive. I usually order kits and components from the US (but to order an amp is much harder and you pay a lot of taxes for it). I can't find any lm3886 kits (from USA) so if you have a good one (the cheaper the better) and I also prefer a 80-100 watt power amp (cause it is ss it it is not need to be at high volume for gain so I can use a high watt amp at home too right?) . Oh and I think I'll build it at one shot but in pieces because it will be easier to debag (I never debagged anything caues til now I got lucky).
I added a schematic


Okay I found a kit: http://www.chipamp.com/lm3886.shtml
1. which one should I buy (mono kit/stereo kit/dual mono kit)
2. How much watt is it?
3. in this pic http://www.briangt.com/gallery/lm3886amp/proto_amp_5 there is alot of other stuff. Do I need to buy it or does it comes with the kit (Also what does each one of them do? (I only recognize pcb and one pot)

Oh and what about the two channels form different amps (U thought of tech21 trademark 60 cause I am not sure if the clean channel of the randall with a ts is good enough for SRV blues )

I am writing from Israel.

I decided to build the randall rg80\100 es preamp (with both clean and dist channels) with poweramp kit (by the way which one do you recommend. I want it to be good for gigs\home\and to be able to play with drums).
I found a schematic but it is very complex and I can't isolate the preamp.
Also I don't know how to power up the power amp+preamp from one saurce?
Oh and how can I cancel the reverb (but leave the fx loop).

Oh and can I build the preamp with the rg100\80 dist channel and the clean channel from another amp with better clean (more fender clean for blues and funk mostly).

It's a problem for me to get a broken Bandit cause I don't leave in the US. Also I am not sure I would be able to design such big pcb (I mean not small as a stompbox). Also what about the  randall cause I like it's sound better.

I found some schematics and pcb but I am not sure if it is the preamp or the whole amp.


http://www.about-guitar-amps.com/guitar_amps_schematics/Peavey/Peavey_Bandit_112-2.pdf

Also how can I erase the parts from the pcb so I can use it

(the username is:amp and the pass schematics)

Hay, I want to build a peavey bandit 112 redline or a Randall RX120D
I build a couple of stompboxes but never an amp. I am looking for the PCB and the schematic but can't find one (for both). If anybody can help with the schematic and the pcb and also give some instructions I'll be very greatful.


Oh and for the randall a 60-80 watt ver will be good too.

Can any one help please?
