Thats what I thought , its stating use a milivoltmeter so it would lead to RMS being correct, however if i use rms for both input and output , I cannot get the results I should at all . Something very bizarre is going on with this deck for sure . The transistors on the playback cards have been replaced for BC550`s so they should all be good . The caps have been replace also , using the test point inputs there is nothing in the way really . A real head scratcher for sure .

I`m putting 333 Hz in @ 330mV RMS , and I`m getting out a MAX of 750mV RMS at the monitor output with the VR`s fully wound open but its calling for 1v

I sorted out the 50hz thing btw , the ground lead for the function gen wasn`t quite connecting .
