Re: Suhr Reactive Load [schematic]

I'm going to do a test of running a clean sine wave thru it via a clean solid state amp, and see what happens.

Re: Suhr Reactive Load [schematic]

Also, you can audibly hear the sound of your guitar coming out of it when pushing alot of power into it. I'm not sure if it's coming from the fan being modulated, but that's my best guess, considering that it's powered only by the input signal.

Re: Suhr Reactive Load [schematic]

I was just playing an old 50w Traynor head into this thing. Plugged into real speakers, the amp is clean and powerful. Plugged into this, it's almost impossible to get a clean tone. Can't barely turn the volume past 2 before it starts to distort. Now I am very strongly suspecting the diode in the fa...

This would probably work great. At least it's worth a shot as the first thing to try.

Re: BAJA Highway 1 [verified]

Thank you! I'd like the idea of this circuit, but I don't know if I'm going to build it so soon. Does it sound close the DS-1? I just see that eq is difference and not scooped like the original DS-1. No demo anywhere, I guess. Seems to me the different clipping diodes will give a different tone ove...

Re: 6V6 Mystery Amp

Pair of 6l6s wouldn't really use a 5y3. Princeton's run 420v on the 6v6s so I wouldn't be worried. There might have been a separate tuner so extra tubes would draw more filament and plate current , that would bring the b+ down a little. What is your filament voltage now? Is it a older 5y3? Edit, I'...

Re: Suhr Reactive Load [schematic]

This would be my pick to try for a potentially better line transformer: https://edcorusa.com/pc_series
I've used these for isolation transformers in my A/B and splitter boxes and they sound great. I have one in my parts box, and I'll see about coming up with a way to do an easy comparison.

Re: Suhr Reactive Load [schematic]

I'm definitely trying this, possibly with toroidal inductors? What you guys think? You could try something like this: https://www.parts-express.com/jantzen-audio-068mh-16-awg-copper-foil-inductor-crossover-coil--255-624 But I think it's unnecessary to use anything this fancy.

Re: Amp switching

Check out the schematic for the Peavey VTM-60 to see an example of a DIP switch used successfully. Regarding LDRs for the channel switching. The SLO and Ampeg VL-1002 are examples you can look at. How it works is that it uses the variable resistor as the switch. When the channel is "off" the resista...

Re: Amp switching

+1 to depends on what you're switching... For things like channel switching, relays work great. They don't have to be large or heavy duty. There shouldn't be any high DC voltages present on them because you would ideally have the switching happen after the coupling capacitors. For other things, like...
