If it was around this area, I would've bought it, without hesitation. Great find! |

The firm is still in business, of course, they're not building that kind of equipment. Displays for the gaming industry.
They started in 1925. |

That looks like a great console. This is nothing like taking the back off to confirm what a fine set of matched components you got
The platter mat on that record changer looks identical to a 1963 Zenith changer I'm working on now. The control levers and tone arm are nothing like it though. Very interesting. The 7868 was not used often and I only recall working on a Fisher 400 that used them in push-pull.

Thanks Guys! and especially DieselJeep I forgot about these old stereos using good parts in them. The Horn tweeters had a warning sticker on them about disassembling them will void the warranty, and said Jensen Mfg co.
I hooked up a pair of RCA cables to the tape input and connected that to a rca fem to mini audio plug and hooked it all up to a Ipod. Now my niece thinks the stereo if the coolest thing ever! |

Chromed chassis and two large speakers, variable IF band-pass. The largest models used PP 6L6's, the smaller models used 6F6's with a triode connected 6F6 as a driver stage, two stages of IF's etc. |

The dials on the set make a lot of noise when I turn them to adjust volume/bass/treble. Sometimes one channel will drop out entirely until I get the dial back into a sweet spot. Any suggestions for cleaning up those connections? I am a total novice when it comes to radios and electronics, so would appreciate any suggestions. |

Spray some electrical contact cleaner in to the gap where the terminals are on the potentiometers on the inside of the unit and and turn the pots end to end a few times.
I recommend De-Ox-Id as your contact cleaner. I use it, and find it to be a good balance of high effectiveness and low price. https://www.google.com/search?q=De-O...utf-8&oe=utf-8

The Penncrest name started being used by Penney's in early 1963. Down in my area, there was a tube stereo that had a jPc logo on it. I know it's late '50's or early '60's, but some youngster who isn't even 30 yet said "It's not Penney's, it would say Penncrest on it if it was. They did offer electronics before using the Penncrest line name.

IIRC, it was one of those one or two tube jobs, with a VM changer. |

Be aware that this unit is creeping up on 60 being years old. The paper and electrolytic capacitors may still be good. but they go bad with age, use (worse yet extended disuse), and storage conditions...You should consider replacing the capacitors on the amp and tuner chassis. Also the rubber on the changer (motor mounts and idler wheel) can go bad from age too if the motor spins but the platter won't, won't at the right speed or there is regular rumble overtaking the audio there may be bad rubber. The cartridge and styli, as well as tubes may also wear out. It may be fine now, but vintage electronics just like vintage cars, only survive multiple decades of use through periodic maintenance.

Cool! It looks like a slightly newer model than mine. Is it a transistor model? mine was tubes but the layout looks like it was done by the same engineering team.

Mr_fixer check post 15 snapshots and you will see that it is indeed tube power. All the best,Tom.J
