HH Scott 350 fm tuner


Hi,
I just bought a Stereomaster 350 tuner in good working condition. I went to someones house to pick it up and he had it playing through his desktop sized speakers but that was enough to decide that it was worth the $100.00 price tag.
The problem that I had in setting it up is that my cable rca males are too large for the narrow and close together rca female inputs on the back of the 350 chassis. I was able to partially plug in the monster cable ends but I'm getting very low volumes so I had to turn up the volume on my ASR Emitter II all the way just to hear anything. I'd rather use the Monster Cable than a $3.00 cable from Walmart.
I'm wondering what other people have done to remedy this problem. My initial thought is to find extensions that will fit on the end of the Monster Cable but will also plug into the Stereomaster however my question being, which extensions and where do I find them?
Thanks!

There are some modern ICs that are minimalist design and not overbuilt and will work fine with vintage gear, FWIW.

DNM Reson is my preferred IC and will fit most anything if desired. Would work nicely with vintage gear FWIW.
The problem wasn't exactly the connection as I had thought. I found a pair of right angle adapters for less than a cheaper interconnect cable at Radio Shack and at a certain angle, they both fit tight.
My problem is that I don't have enough neutral between the tuner and my DAC. They're somewhat close together but not so much so that I could have envisioned this to be a problem. So what to do; disconnect the DAC interconnects at the back of the amp and the volume increases exponentially.
Fortunately I don't listen to a a lot of radio so I won't have to go through this routine very often.
Anybody know where I can find a 350 Stereomaster manual and schematic? I'm thinking about comparing the multiplex circuitry with the 310 E to see if if I can modify it in the 350 as well as other tweaks (by my tech.). I'm assuming that now the 350 is probably operating at around 50%.
You can find schematics for the 350-B, C, & D at HHScott.com. You MIGHT also be able to find a manual at the same site, via this link, if you have Java Runtime Environment installed.

I have no idea what the first two sentences mean, but it sounds like the input select function of the integrated amp may have a problem, and is shorting the inputs from the two sources together.

Also, this owner's manual addresses the 350 series to some extent, as well as other Scott tuners.
