2. If I've got that right - why a TL072 if not using a tranny? It is all a question of how much current the opamp will draw. Resistor Phantom powered DI http://www.jlmaudio.com/JLM%20DI%20kit%2048v%20Simple.pdf 48v Phantom power is sent via 2 x 6.8k to the DI which also has 2 x 6.8k resistors. This...

Hot off the bench. A champ guitar amp miniaturized from the original 6SJ7 and 6V6 to a EF86 and 6AQ5. Runs on external 12v SMPS and has internal DC to DC to make the 350v rail. Power on lamp is blue leds under the tubes. Sounds great

How smokin does that look! Don't happen to have the files for the engraving handy?

Yes what format would you like the engraving file in?

I do like the push button switch on Joe's - is that switch illuminating, Joe?

Yes it is the same Red led switch used in the HAL project prototype box.

These are a couple of BA1's we have made in the Hammond cases. http://www.jlmaudio.com/BA1%20front%20400.jpg http://www.jlmaudio.com/BA1%20Back%20400.jpg I like these cases but they are not cheap and the screws strip easy and come loose so we change them to longer different type ones to keep the box...

So changing level and pressing the same switch again the CPU will remember a offset for every switch which is good for spe...

dINgO PCB's are due to arrive here on the 16th of March.

The simplest kit to build we have ever made. http://www.jlmaudio.com/Zener%20Reg.jpg + http://www.jlmaudio.com/48v%20380mA%20SMPS.jpg This kit used with our prebuilt 48v 380mA SMPS power supply can make a 24v rail and 48v rail to run 2 x neve 1272 / 1290 / 1073 modules or V672 Telefunken modules wit...

BAD PCB's are due to arrive here on the 16th of March and full kits will start shipping on the 19th of March.

Power rail splitter which makes a virtual centre ground out of one a single floating power rail.



Used with our 48v SMPS power supply it will turn the 48v floating rail into +/-24v with a centre 0v ground to run bipolar rail devices.

Great example of using the JLM DI as a external phantom powered DI.
Thanks Chris for putting a copy up here

Thanks for that Chris. I had planned on doing that so you saved me a lot of time

Beta Testers can be anywhere. The world is one place as far as I am concerned.

If you are living on the space station I might have to check on freight costs first.
