1964 Zenith console with drop-in tuner
« on: May 26, 2016, 11:09:55 AM »
The local Habitat ReStore is where I take minimally-functional consoles which still has value for someone. A good example is my 1966 Silvertone SS console that had needs (germanium transistors and unobtanium changer parts) not worth the time of a collector that has more interesting stuff lined up to restore.

This time a treasure was found. I saw it last week for $50 and figured if it lasted a week, that was a sign to bring it home.  This Zenith MT1971 in a very nice walnut cabinet with twist-on legs and six speakers inside. Not a TOTL tubed console but one with a single-ended 6BQ5 stereo amp with bass-boost switch and an MLT15 stereo tuner with its own power supply.

The record changer was a V-M of course but had no markings on it like most Zenith's do. The cartridge looks like an Electro-voice 150, similar to what is used on Magnavox Micromatics of the same age.

I was able to offload it into my basement studio and its next to a 1959 Zenith from an earlier post. Ill post some pictures next.

The changer that came in this Zenith has an EV186 cartridge, which looks like an E-V 150 but has an adjusting screw at one corner ??? - is this an anti-skate or azimuth adjustment?

The changer is dated 6507, is in above average condition and plays records well but I'm swapping it with the 1970 Zenith Super 2G-branded V-M that was in my 1959 console.

The 2G changer will be closer to the Zenith-branded changer what the 1964 came with originally. One thing the 2G hates is very worn records, more so than the generic V-M with the heavier tracking EV cart.

Everyone seems to love the 2 gram changer, to me it is too sensitive, just shutting the console cover while playing or walking near the set will cause the stylus to skip, the springs are so sensitive on the changer, that after the record drops the tone arm will skip due to the springs still moving from the changer action...

That is exactly what happens. Even on new vinyl :( Most V-M changers have foam cubes stuffed inside the springs to dampen such action. I just replaced the dried out ones with cubes of foam "bug-strip" (sold for window AC unit installs) and am hoping for improvement. Since the 2g is now in my 1964 console of this post, I need to work on its amp before I test it. First thing to go is that 4 amp fuse - WTF was Zenith thinking there. Schematic claims the power transformer draws 110 watts. I'm thinking 2 amp fast or 1.25 amp slow fuse here. That is just to get started. Ill do a separate post in Repairs/Tube consoles.

Zeniths of all vintages have an occasional nasty habit of blowing up transformers

It is earlier than 1964 if it has tubes.  By then everything was solid state.

Zenith still made some all-tube stereo consoles through the 1965 model year.  They were also among the last to switch to circuit boards.

yes get rid of that 4 amp fuse.... I was told since both chassis, tuner and power amp... not to mention the turntable, all go thru the main transformer hence the 4 amp fuse, but it is too high, my transformer failed... the primary winding fried and fuse did not blow...
