Hey Jim,groovtubin wrote:I do my own thing w/these amps, not exactly like dumble.
Would you be able to elaborate on your tweaks, especially to make it bloom and sing with a Strat?
Regards,

Re: Fuchs ODS too spiky on the treble side
I love my Fuchs Bassman ODS100!
Edit: Andy also promptly responded to a question I had asked him about the amp. Can't beat that. Thanks, Andy.

Re: New ReleaSSSes
Thanks all for the quality content and discussion! This thread is a real treat and the featured amps sound great. A quick question: can anyone see a reason why it wouldn't be possible to develop the appropriate bias for the dc follower using 80s twin iron, which uses a bridge rectifier, simply by ad...

Re: The Mods thread.
Hi Mark, I'm curious about this and wonder if you would mind elaborating a bit.Mark wrote:I also found there was a significant difference using 250K pots in the tone stack (per the Komet) than the Express' 1 Meg pots.
Many thanks,

Re: Just in case you don't think careful building matters...
If it's not too much trouble, Prspastor, would you be able to post some pics of these amps? The lead dress on my first amp--an 18 watt---was pretty goofy. It had a pretty brown sound and was light on gain. After I cleaned it up it got very bright and gainy. The coupling caps were 715P because Mallor...

Re: New ReleaSSSes
Thank you for this amazing work. The preamp schematic resembles ODSR #13 quite a bit: http://ampgarage.com/forum/files/odreverb_902.pdf Of course there is much more feedback here, along with the two tube mixer setup. One question: on V4a+b cathodes, usually the R/bypass C combination is elevated by ...

Re: #124 NFB Resistor
I've read a recommendation that in the (sensitive) grid stopper position a resistor with little inductance is important. I employed the "hifi" trick of testing resistors with a magnet and while the metal films and carbon comps didn't stick, the carbon films did. I'll be ordering both carbon films an...

Re: Steel String Singer Layout?
Some gut shots of the sterling made their way on here a while back--from ebay if i'm not mistaken--and it's tough to tell what's going on with the filters. Folks have said to consult chap 5 of Radiotron v4. If anything that info could be transformed into a proper approximation. One thing I wasn't co...
