Hi all,

I've just purchased a B&k dynajet model 607 from a flea market it does'nt seem to work like it should, i'm not getting any meter readings at all, even after making all the settings by tube type.

I was wondering if anybody has or knows where i can get a copy of the schematic , it would help me a lot to troubleshoot the problem.

I hope its not the power transformer!!

BTW i did'nt pay much for it and cosmeticaly speaking its in a very good shape.

Thanks

Jeanpierre

Tube tester are not usefull for testing amp tube. They don't have enough voltage available like in the tubes amp ( 300-400 volts) . Only good for a dead short tube or dead tubes, this not happen often.

Best is to have few tubes in stock for the same money .

Short research on Google

Tube testers need to be re-calibrated after being recapped. These are not simple devices to repair. Most are true point-to-point bird nest mess of wires. Best to find a good tube tester tech (these are getting to be very rare birds).

Sorry, for the news.
