The pulse generator was built here in SanDiego I love the case and knobs. All aluminum anodized and V-honed to give the flat look.
The scope is going to have to be re-capped, there is quite a bit of jitter in the triggering circuit. I think the pulse generator also needs a bit of work.
I have tow Tek 475s in the garage both not working, one was a parts mule to get a third 475 working The other one in the garage is in fairly good shape and has a DM-44 attached to it.
