Trascendent Sound Grounded Grid preamp

I love equipment that over-achieves. Is this a "giant-killer?" How good is it? Has anyone here tried this unit? One of my favourite"cheap" preamps was the discontinued N.E.W. P3-single -ended preamp. Correct me if I'm wrong but I think this was a Cary-based design. If you have a favorite "inexpensive" preamp, list it, tell me why and how it compares. The idea here is cheap, good sounding and fun.....regards, Bluenose

The GG is a superb little pre. It is very quiet, transparent and revealing. As you may already know there are no knobs or remotes to clutter it.

I built mine from scratch and incorporated a number modifications.

The GG has a DC filament with a voltage regulator. I eliminated the voltage regulator and used Schottkey diodes and a couple of resistors like snubbers to reduce voltage for the filaments.

I used UF4007 diodes with snubbers for the main supply.

The input specs a 10K grid stop resistor. I used a 68K tantalum resistor with an Alps pot in shunt. Used tantalum resistor for other resistor in signal circuit.

I tried Auricaps 3.3mfd output caps. It could possibly shatter glass with the Auricaps so I used Jensen copper foil PIO caps to tame it some.

I don't know about the extra output but I would imagine it is possible. I have only one in and one out. There is an on off switch and the volume control, that all.
