Re: "EF86" sound from 12AX7 tube?

Seems like they just got tired of dealing with the EF86's shortcomings. If I wanted to get rid of the EF86 while keeping its high gain, I would replace it with a twin triode configured as a cascode. edit: thinking alike, I guess.

Re: Therians

Nature vs nurture . The debate will continue . The old Native American saying comes to mind : “There are two wolves inside everyone, a good one and a bad one. Which one wins ? Whichever one you feed” Apparently I fed the wrong one jalapeño poppers last night and it took the form of a rabid badger t...

Re: Earthing and lead dress

10mV is well minimized, but what is the source? When that is identified it can be not just reduced, eliminated. Even low level oscillations will heterodyne with signal to make the signal less pristine.

Re: First amp build questions

If that's the case, i would improve all the grounds, resolder ground wires, sand connections at jacks and pots, clean with solvent and reassemble. That might kill your oscillation.

It looks like a Mont Blanc Kester 44 model.
You sure? Looks like a personal massager. Maybe?

Breadboarding

When breadboarding new circuit designs, instead of just looking at waveforms and using headphones or jockeying a safe interface to rig it to an amp for testing. I clip the output to one of these wireless units and send it to my shop amp. No ground loops, level issues, long cables, etc. They work wel...

What's patentable a geometric shape? Could you alter the size and color of the diamond pattern? But is it worth the headache... Diamond sounds pretty bitchin', tho. Commercial availbility of the pattern would put the claims at risk. The stitching and color are noted as components of the claim. If w...

I did buy a NOS sports car, that was about as wise.
