DIY projects

This came to my mind. It would be super interesting to know what DIY projects you guys have done !! Every DIY builder could share their projects and tell about them in this thread !!!

I've build a great mountain DIY projects.
What DIY stuff I presently have in use are:

- 10 CH graphic EQ (based on EH-7000)
- 4 X 12" Eminence cabinet 325 W (3x 75W and one 100W)
- 8 unit rack
- 4 channel pedal switch for Marshall JMP-1.
- 100W solid state amp for vocals

Also our second guitarist has some equipment made by me. And of course my guitars have had their own treatment

Some pics of my DIY projects

Tiny guitar poweramp (2.8 - 3W, sound REALLY good, use it all the time):

Soldano X88R (doesn't yet give me the sound I want, but still sounds good):

Practice single-ended amp (High Octane, sounded good, but was morphed into Soldano X88R crunch channel):

I've build a tube amp based on fender 100W schema in school back 7-8 years ago. I made it for my teacher and he bought all the stuff.

I was about to build a 50W tube amp, but components are so high priced in Finland that It was cheaper to buy used 50W JCM800 !

How much those amps costed you ?

PS. I like Sovteks too

2 spacenuke: Nope. And there ain't going to be any. Out of ten people one will say it sounds like crap ('cause my miking skills leave much to be desired) and three will say my playing sounds like crap (which I completely agree with , I'm not Vai by any means).

2 MorbidDream: It's actually cheaper to buy a ready-made amp even here, if we aren't talking about "boutique" stuff like Soldano, Bogner, Dumble and Trainwreck. Dumbles sell for $10K (I honestly don't understand why), and you can build one for less than $800 with all the same parts & stuff. It is not guaranteed, however, that it'll sound the same. It's cheaper to buy a used Mesa/Boogie than it is to build it by hand. Some vintage amps are just too bloody expensive to buy and it's less expensive to buy them by hand, too. They won't look authentic, but they will sound like a real thing.

100W is WAY too much for 99.5% of situations. In fact, I can't even turn my low-power power amp to the full volume, because it's too darn loud for home. And 50W is too loud, too. Many people don't know that, but the difference in volume between 100W amp and 50W one is very small, much, much less than 2 times as one might think.

As to what did it cost me to build this... I don't know exactly, I need to check with MS Money file. I had to buy everything, from drill and soldering iron to tubes, turrets, capacitors and wire. My estimated cost for X88R was around $600 (that's only parts, shipping, etc), maybe a bit more (cost of my time is not included ). High Octane was around $250. That low-power amp was around $130-140, maybe a bit less. I'm also going to whip up a design of my own - two tube four stage preamp, JFET/MOSFET active tone control, JFET/MOSFET effect loop, all tube low-power power amp. Too bad I don't have much of free time on hand right now.

Yep, I know 100 is way too much ! I've had problems even with my 50W JCM800 (well, atually just once)! Just too much power.

Well, we have same situation then. tubeamp building is very expensive. Those AX84 projects are quite reasonable and practical for home or studio use. I found that the most expensive parts of tube amp was transformers. The actual costs didn't differ much if you were building either 100W or 10W amp.

Your future project sounds good. Informate us if you have possibility to start it ! I've build also tube preamp. They're more reasonable to build than amps, espeacially when thinking the costs.

I forgot to say that I liked your calligraphy !

BTW, my home amp is DIY 2 Watt solid state amp

The schematic for that power amp is here: http://www.winisp.net/dmitriy/pa.pdf

X88R modified schematic is available at its web page (see the link in my post above), unmodified - everywhere on the web.

High Octane schematic is available from here: http://www.ax84.com in several different flavors.
