> Boy, that brings back memories. But you forgot All Zeros. Dial receiver 
> to 00.000. You should peg the Carrier Meter. Flip the BFO on to see if 
> you hear a tone. This checks everything back from the headphones to the 
> First IF Mixer (you are receiving the 17 MHz LO). If you have the meter 
> pegged, then everything from V202 on is working, at least to some 
> extent. That leaves V201 stage and the Antenna relay.
> Back in the day, it was common to troubleshoot down to the stage while 
> the receiver was still in the rack, then just drop the proper tube in 
> and move up the PM schedule.
