hi Dubbers.

i just bought spring reverb tank + preamplifier from old GEM wizard 325 organ. i want to make standalone open unit for thunder fx but i can't find schematics. could anyone help me with it? where should i add power supply (and what voltage) and where connect outputs.

here are some photos: http://www.flickr.com/photos/67247286@N ... 618437818/

thanks in advance
