Look it up, and see that it's perfect for the job - it provides some 30 dB gain without an input up-transformation and with a larger AGC range. Is the SL312 still available? Texas Instruments' TL026 is still new from DigiKey and Mouser, even through-hole parts. Av of 55 and 50dB of AGC range. Cheers, Dana K6JQ My error - the IC mentioned should be SL612C and nowadays it's available from China via eBay: http://www.ebay.com/itm/120922014405... 4.m1497.l2649 It has a much wider AGC range than the TL026, up to 70 dB IOW higher than the stage gain.
