I owned a TT PS for awhile, but it had a single pass transistor without the OVP
module ( crowbar ), so fear of putting 25 VDC into the rig from a 30-year old
transistor failing caused me to never use the thing. For awhile I contemplated
building a crowbar, but ended up selling the PS, now use a switching supply
with meters and just keep the current levels below the danger point.
When did Ten-Tec start incorporating OVP ( and/or dual pass transistors )into
their power supplies? Which models are "safe" from the destroying the powered
device because of single-component failure? So far, I've avoided buying any TT
power supplies because am never sure which of them are "safe".
