This is development of my simple GC preamplifier that I made some time ago. Now it's two, or even three in one :D

Preamplifier
Just a simple preamplifer using single op-amp.

RIAA preamplifeir
Basic preamplifer updated with few components working as a RIAA correction. This section is basing on VSPS preamplifier (great work RJM!). When it's made as dual mono - second board can work as another gain stage in this PRE or output buffer. This should bring to live my analog ;)

Supply
Simple supply. Two fixed voltage regulators + CRC filter.

An externally hosted image should be here but it was not working when we last tested it.

Well at the price Veteran charges i don't mind drilling myself

I also don't mind to drill them myself, I was just curious.:)

Just wish i had mine, realle feel the urge to build a better RIAA than i have now

I won't post a picture of my boards than, I don't want to upset you to much. :D

Edit: I was a bit hasty with my comment. They are drilled but on the component side the holes are covered with a kind of film (soldermask?). You can easy punch it through with sharp point.

Please don't post pictures, i might be in need of a shrink then :)

Well, it sounds like it's the soldermask covering. no problems then.

all the best
