Forum,
Looking for discussion, recommendations, mfr/retailer on solid state vs NOS 6V vibrators. I assume that vibrators fail regularly, but orig Radiart S-1 hums and provides primary current to the transformer, but waveforms are asymetrical and not even close to being square wave like. Set has been recapped, although many failures/out of tolerance/wrong value components are still there. Help.

Marv,

As far as I know all the solid state vibrators sold by AES, Radio Daze, etc. are all manufactured by Schultz of Antique Automobile Radio in Florida. Web site:

http://www.radiosforoldcars.com/vibratorsF.htm

By the way, there is a handy battery polarity chart on his site also. All 6 volt Mopars were positive ground, to my knowledge.

The car club "Packards International" has a program where they will send your vibrator to a member who will rebuild it in solid state. The price is somewhere around $50 plus shipping. Said rebuilt vibrator is said to be bullet-proof and voltage/polarity insensitive. I have not used one of their rebuilds, so cannot recommend it one way or another.

Perhaps someone else knows of another manufacturer of solid state vibrators?

Most 6 volt tube auto radios with vibrator / step-up transformer / rectifier tube will work fine if the vibrator is bypassed, feeding six volts AC directly to one side of the power transformer. That is to say that these radios may be powered from the 6.3 VAC winding from a transformer having sufficent amperage to power the radio (old TV power transformer), rather than from a DC supply. This will at least get you through repair and test without a vibrator, and 6.3 VAC may be easier to come by than a DC suply, if you decide to leave it this way.

Mag/Ed,
Thanks for the tips. I hadn't thought of the 6.3VAC to transformer primary. The quoted current drain of 9.3 amps @ 6V w/vibrator is pretty hefty, but how much is used for the actual vibrator vs filaments and transformer? I put together a 6V dropper from case, fans, heatsink and transistors of a faulty PC supply yesterday, using an LM317 driving 2 power transistors in parallel. Used a piece of heating element (1 ohm) as a 6A load, and it seemed OK, even red hot. Today I'll make a 10A load from a stack of power resistors for final tests. Film at 11!!

Sorry no videos. Well prelim results indicates the dropper is working at or near 10A. A home brew load (0.6-0.7 ohms/100W) was sourced with 6.3VDC, and didn't melt down or get red hot. Transistors and LM317 heatsinked between 2 fans didn't meltdown either, although warmed up a bit dissipating the 60W. Didn't measure actual current, because leads and meter shunt alter current path and measurement accuracy.

Here is another strange phenom discovered yesterday. Since both my DMM's are limited to 750VAC, used my trusty Micronta analog VOM (1000VAC scale) to measure the open circuit transformer secondary voltage while powering the old vibrator (no tubes) with 5V. I Had already replaced the open buffer cap with a new 0.0033uf/1600V orange drop. I guess the open ckt secondary (spikes) exceeded the capability of the meter, because it no longer works.

I have fried a couple DMM's in the exact situation.

ANYBODY got a schem for a Radio Shack 22-204U analog VOM, so I can fix the one I smoked?

Didn't work for me. Vibrator wouldn't start/run well 'til I cleaned off the grease.

THE NEWS IS IN, but no film!!!
Radio plays, needs alignment, and voltages are about 5% higher than schem shows. Riders tube layout is different than my set, so distrust other info as well. Solid state voltage dropper works fine, but need a good shunt and ammeter to avoid tying up my bench meters. Vibrator repair and adjustment worked out well, although recommendations for next failure will be to replace with a solid state version.

Never use any oil or grease on vibrator points. De-grease them.
