It looks like all the wires going to the subchassis can be unsoldered from the MAIN chassis area - they all appear to go to tie points. It then APPEARS that the RF chassis can be removed. Looks like the sides can be removed, which would allow somewhat easier access. I have no done this before.

***It's not really that difficult to remove the RF chassis. First there's the wires- perhaps 8- just mark them in a sketch. Remove the dial. Next come the screws that hold the right side of the chassis on- once they are removed, the right chassis will swing out an inch so as to clear the RF chassis rubber mounts.

BE VERY CAREFUL WITH THE BAND MASK!!! IT HAS NO PROTECTION ONCE THE RF SECTION IS REMOVED!!

Once you have removed the RF section, you will see that the side covers are held on by screws on the top of the chassis and front and rear. Once the side covers fall off, you have full access.

Not too long ago I had a particularly nasty 37-660 (same chassis) that had been mutilated and miswired, along with RF switch contacts bent outward. It took perhaps 10 removals and installations of the RF section before it worked fully. It took about 20 minutes to remove and install the RF section each time. The end result was worth all effort. A super receiver with great sound. [/b]
