be sure the pins are clean, they burn. Cold joints were a big problem that
often blew the power supply board & sometimes started chain reaction
failures. When thats all done they were very good sets.

Apologies for bumping an old post; just wondering do you guys have any information about the power circuitry of the T991?

For example, I think the power circuitry is either internal or chassis-mounted with only the power lead visible on the outside and no external power brick - is that correct?

Also, would you have any idea about what the output DC voltage and amperage would be?

Many thanks
