Radio City Products Signal Generator Model 705A

Hello, this is kind of a follow up thread to the Heathkit SG-8 Thread that was kind of getting really long and was also starting to become a wild goose chase so to speak with all the issues that I was having with it.

At the same time I bought the SG-8 I also bought a Radio City Products (RCP for short) Signal Generator Model 705A.

When I got it, I opened it up to see what the condition of the guts were and sure enough it was all original paper caps inside the unit.

There was only one repair done to the unit and that was the filter caps, which I'll give them this much, at least they took the original ones out of the circuit and out of the cabinet, but they did a terrible job with installing the replacement caps which was a cardboard tubular job that they unsuccessfully attempted to screw and solder the mounting bracket to the chassis, then proceeded to solder the ground lead to the capacitor's mounting bracket for the ground, and then attached the positive leads to their respective locations.

I'm surprised that the unit worked that way, and didn't short.

I replaced all of the old paper caps and the old improperly installed tubular filter caps which cleaned up the look of the underneath of the signal generator's chassis quite a bit from what it originally looked like.

This unit has a high and low RF output, with the Low RF Output being of the old Mic Jack variety like the Heathkit had, which has an adaptor with it that goes from the mic jack to an RCA jack which I was able to order a Phono to BNC adaptor from radio shack that I can use to make this unit work with my test cable I have.
The RF High output is a Banana plug that I was hoping to somehow devise a 50 ohm BNC cable that had the BNC plug on one end and a Banana Plug on the other end so I could use that RF high output as the monitoring output for my Frequency counter because the RF High Output on this unit isn't affected by the Attenuator according to the manual.

The AF Input/Ouput is also a Banana Plug and then there is a Ground connection which is also a banana plug which I'm assuming its for all of the banana plug connections on the unit.

below are some pictures of the unit in question as well as an ad for the unit that I dug up online, I also have a manual for it as well but its too big to upload on here so if you want to see it I can just email it to you.

Thanks.
