Amplifier Discussion / Fetzer Ruby problem
August 04, 2007, 12:22:02 PM
Just worked up a Ruby with the 'Fetzer Valve' mode from ROG.  But now I can't get it to work at all.  All I get is a hum.  If I turn the volume pot down all I get is a motorboat noise.  I've retraced the components against the schematic and don't find anything wrong.  Any ideas where I should look? 
Amplifier Discussion / Battery power supply?
July 16, 2007, 03:05:20 PM
I recall having seen (somewhere) a schematic to build a bipolar power supply using batteries.  Anyone know where that might be? 
Preamps and Effects / Whisker Biscuit
July 08, 2007, 12:18:34 PM
Anyone built the Whisker Biscuit off the Runoffgroove site?  Are the cap values for the 0.1 and .0047 caps micro-farads or nano-farads?  It doesn't say. 
Amplifier Discussion / Hiss
July 06, 2007, 02:50:44 PM
Just finished my starter project.  The Noisy Cricket from the Beavis Audio site.  Finished debugging it and it works okay.  But I have a hiss in the sound.  And this circuit has a 'grit' switch, but the switch seems to make little difference other than upping the overall volume and hiss levels.  Any ideas on where to start? 
Amplifier Discussion / Frontman issues
June 16, 2007, 10:26:36 AM
I have a Fender Frontman 15 that died.  It was a couple years old so no warranty, so I think I'll either use if for parts or try to troubleshoot.  I can't get any sound because it blows the fuse the instant I switch the power on.  I decided to disassemble it and I don't see anything burned or charred.  Any ideas on where to start looking?   
The Newcomer's Forum / Cabinet simulator
June 16, 2007, 10:07:14 AM
Going to try to make a small amp primarily for practice.  And I'd probably want it just for use with headphones.  I see the cabinet simulator (like the Condor in ) and think that might be a good addition.  But does that go on the 'input' side of the amp (basically, the output of the cab sim would run to the input of the amp) or does the amp output go to the input of the cab sim?
