Does anyone have any info on a differential front-end RIAA preamplifier using 12AX7's that appeared in Wireless World/Electronics World. Author was Morgan Jones.
There is a diff-input amp in his "Valve Amplifiers", but it was very complicated and used a lot of difficult-to-obtain parts.
If anybody knows something about this amp, I would be very grateful!
Best,
Bob McIntyre
