Replacing link cable in 1950s Blaupunkt Car radio

[Old Sparky]

Terry, I'll have to check as to whether I fitted snubber caps. or not. AS I mentioned when I revived this thread, the radio was put on one side for over 3 years. As to the electronic vibrator's frequency, unless it mentions on the company's website, I don't know what it is, and may have difficulty measuring it, but I'd imagine that over the years thousands of these solid state vibrators have been sold, and fitted into a wide variety of valved car radios, so there shouldn't be any pronlems caused by using one. I've no idea what the internal circuitry is, other than there being an oscillator of some sort, and they're sealed units, so I won't open one and reverse engineer it. Re-reading my old posts reminded me that the original mechanical vibrator was missing from the Frankfurt, which is why I bought the solid state one. Checking the Antique Automoblie Radio Company website, it seems that their solid state vibrators operate at 1Mhz. I've used them in other vintage car radios without problems.
