Yes it certainly has! I posted an article on the Vidor 369A a good while back. It is a very good performer but the mains EHT is dangerously exposed and is definitely a none starter.

I plugged it in a few moments ago and it worked without adjustment!
Hope you have success with the 991T. The flywheel sync is very stable once you have evicted the leaky .01uf caps in the discriminator circuit. It has a large component count and you will need quite a few caps. Regards, John.
