[Test-Equipment] Hickok signal generator

[Carl]

My experience with "service grade" sweeper/SG is about nil as Ive either had 
access to lab grade at work or built my own collection of now affordable 
gear mostly since retiring 12 years ago.

I dont know how it is up in the boonies were you live but down south is a 
goldmine of belly up auctions should you want to upgrade. Out here is 
similar.

My own project today was getting started on a 50 year old HP-606A that 
started acting up, looking at the PS with a scope reveals pure uglies! And 
even one of the 12B4 regulators has an open filament, but for $30 Im not 
complaining....its easy to work on with common tubes and early film caps and 
A-B resistors that are still perfect.

I might try restuffing the can electrolytics if they come apart easy, 
otherwise just put singles wherever they fit and arent heat blasted.
