For the next project, a 24V power supply is required. But no transformer is needed. The big, heavy, separate regulator (LM7824) should be added etc etc … And the consumption is just a few mAs. Well, then be DC – DC converter! The point was that 12v should be converted…
Okay, this is a great product of the Princeton Company. This is PT2399 echo IC. It can make good guitar effects like: delay, reverb .. But if it’s original .. Well, we got a fake IC. No PTC manufacturer, unknown “DTC”. Compared to the original, other exterior. And noisy, such…
Some pictures: electronics repair. The product name: Dynacord Eminent II. This is beginning to be manufactured in the mid sixties. Initially, all tube design, and later the transistor preamp and tone section. Meanwhile, little change in design as well. This four different input and tone control. A small band certainly met…
So far, we do not really dealt with bass guitar effects, amplifiers. Here, in this time of change!One of my favorite band The Beatles, inspired a new tube bass preamp creation.The plates can hear great tunes and sounds of the XXI century it is significant. This’ 60s-edgetone you want to…
It’s a lucky day! We have a piece of the American history from the electronics computing age. It’s not other than RCA Corporation (Radio Corporation of America) 6211 type electron-tube.
Aural Exciter since the 70’s. Do you know that feeling when you’re playing on guitar however you’re missing something? You’ve got many effect like distortion, overdrive, delay or something programed effect. You’re sure something is missing from your music and it’s not other than fatty and lively sounding.

Once again an interesting circuit. Okay, to combine it with a tube preamp and a fuzz face! What happens if a small powerful tube amplifier, and combined with the classic fuzz effect? What kind of sound will be the result?
Well, again, we present a very simple circuit. As is also shown in the drawing, few parts. The circuit is based on a dual operational amplifier RC4558. But this is only half used, so there is only one using the op amp. Alternatively, you create an active tone control in…
