I ask this question because I'm planning to build a tube amp and the only BGs I found for the power suply are 22uf and 150uf. If I used higher values, the power supply would have less ripple but I would have to use "lesser" capacitors. Also, the 350v rating of the BGs limit the design options...

Hello, I'm planning to build a Bijou and I would like to know how it compares to popular tube amps like Woo 6, Sp or Mad Ear+. The only experience I have with tube headphone amps is with the SP PPX3 and Extreme, so those would be useful references for me. Thanks!

Hello, I recently started making my B22, the S22 is already finished and I started soldering the first parts on the B22 boards. However, I noticed that 1 of the 3 boards has V+ and G shorted and the others don't. Did I do something wrong or is the B22 board defective? Here are some pics...

Does anyone know the exact dimensions of the E22? There is a width and a length in the web site but I want to know the exact position and size of the holes. Thanks in advance! Diego

Hello, Could anyone tell me what kind of digital cable the Audigy 2zs use? It doesn't appear to be optical and the termination is not a regular coaxial. Also, if anyone know where to get it I'd like to know? Thanks in advance for your help, Diego

Hello, I bought 2 RCA 6gu7s from ebay recently. I have tried both in the driver position on my PPX3 and both of them make a loud distorted sound once I power the amp on. However, they only make the sound once for a second just after power up and never again until the next time I turn it on...

I have a LaRocco PRII and I wanted to know if any of you have tried the new PSR power supply for it. In particular how do both of them compare to good home amps. I'm trying to decide if I should buy the PSR instead of selling the PRII and buying something like a RSA HR2. I only use it at my...
