Where can I find Schematics for the SX-202 Dual Microphone Preamplifier?

Where can I find a Data Sheet for the SX-202 Dual Microphone Preamplifier?

How does the 302 compare to the discontinued SX-202?

The 302 has significantly less noise and distortion. THD+Noise .007% (1kHz, 0dBu, 600 Ohms out) .01% (1kHz, +22dBu, 600 Ohms out) Signal to Noise Ratio 95 dB (-50 dBV, 150 Ohms in)

Where can I find a power supply (PS-2) for my older SX series unit?

Since all of the SX series which used the PS-2 power supply are no longer supported, Symetrix can not supply and has not stocked these power supplies for a considerable number of years.  Aftermarket power supplies may be available at:

www.rpelectronics.com – part number RP-1601AA1
www.ebay.com – search “Symetrix PS-2”
ww.onlinecomponents.com – part number 420A0008
