Diesel , are you looking at the Monitor radio model M-510 ? Because the rider's shows it using a 1U4 for an IF amp , and this radio does indeed use a 1U4 in that position . I see that a 2.2meg is used as control grid bias for the 3Q4 and see a 1/4 watt in that position , but I still am looking for a 2.2 meg 2 watt in the schematic (In the pictures I posted in my last post you can see the 2.2 meg 2 wat that they installed , but there is only one 2.2 meg 1/4 watt listed on the schematic and it is present between the 3Q4's control grid and ground)
