[TenTec] Hooking up an Amplifier for the first time...

[Ken Brown]

Hi Mike,

That looks like a nice product. I have a couple of questions. The 
specifications list says the relay contacts are good for 2000 mA at 125 
volts. Many older amplifiers have around -150 to -180 VDC that needs to 
be grounded to key them. Later in the text it says you can key the 
Heathkit's -130 Volts. Is this unit using a 125 volt rated relay to do 
that? What about the MOSFET output rated at 250 volts? Can that output 
be used to pull a negative DC voltage to ground? Or will that only work 
with positive voltages?

Thanks,

Ken N6KB
