Hi Dale, tnx for interesting info - i have done this test and ranges on AF and RF knobs are 2-240, so no problem with that. Yes it is an early K3, S/N 28xx. I use Sennheiser CX 300-II ear-canal phones impedance 16 Ohm - maybe is this impedance too low, but accordingly to the data-sheet for LM4811 that should not be the problem. I simply dont know what that could be? 73, Bozidar, S50BN
