I got the SPARK Houston MINI-1998.
However, in order to drive this amplifier, I have to supply power to the amplifier itself from a separate power supply unit.
The terminals on the power cable that supplies this power were unlike anything I had ever seen before.
I would like to know what this 4-pin, round terminal is and if it is possible to get the same one.
I would appreciate any help from you knowledgeable people.
Thank you in advance.

If you cannot find the proper mate, remove and replace it with a 600VAC rated connector
that is mechanically compatible. Please don't mess around with dangerous high voltage.
320DC for the tube plates, and 12.6 (AC?) for the heaters. The designer has chosen a (CB mike) plug to handle high voltage - low current and high current - low voltage in one piece... debatable. A 4-pole speakon might be good enough, but I do not know the upper voltage specification of it.
how much plastic insulation is there between the pin and the nearest ground as in connector casing? if the is phenolic, then it is possible to get its dielectric strength per mil...
Dear Dave
Thanks for the reply.
The PSU was included.
Would the attached picture help?
Wow!
This is a great resource.
If I ever need to create my own cable, I will refer to it.
This is exactly what it looks like!
Can you see what each of the four pins does...?
To put a high and a low voltage supply in the same connector is injudicious......
Best is to use separate connectors.

I have made connectors in a situation where the original was not available, I used mold release spray, epoxy adhesive, glass fiber mesh, and brass pins.
It worked, the motor is useful again, a replacement motor would have cost about as much as a Volkswagen Polo...

IEC 320 C13/C14 (3 wire) from PSU, to DC320V+12.6V 4pins connector on amplifier! How to wire it❓
I have lost the cable that makes that connection and would like to know which pins are high voltage and which are low voltage. (On the PSU side.)
