[Milsurplus] GO-9 question

[howard holden]

Actually with the connectors coming out the bottom, sounds like u have a TBW not a GO9. The TBW and GO9 are almost mirror images at least on the HF side. You can apply female bullet connectors to the bottom connections, theyre almost a dead nuts fit. The TBW/GO9 uses an 803 tube (not an 813!). The 814 will fit with an adapter you make and may have a different filament requirement.  Don’t know any suitable tubes smaller/lower power that will fit.

One way to tell if it’s a TBW is the location of the big relay. On the TBW it’s in the HF and MF sides, on the GO it’s in the power section.

I have the opportunity to buy at very reasonable cost the HF section of the GO-9. It has full covers on all sides, no shockmount.
It appears the power connectors come out on the bottom, so some means of elevating the bottom surface will be required.
My question is, if i don’t want to use the 814 final tube at the 1500 volts it wants to make it happy, does the socket accept some
other lower voltage tube, like a 600 volt tube? I do not care at all about power, contests, and such. Or – if i get the thing – should
i just build a 600 volt supply for the existing tube and call it done?
