Just for comparison, before you drop money, take a look at the MFJ 
4125, 4225, or 4245 supplies.

Having just bought a 4125 about 3 weeks ago, I can tell you that this 
25 amp supply is $84.95, and perhaps a little less in some places.

It is quiet in the spectrum, but the fan does make more noise than the 
one in my 4245, which is a 45 amp model.

The 4125 is a basic model that has no meters. Because of that, it is 
about half the height of the 4225, which is the 25 amp metered model.

The one I bought uses the 5 way binding posts, but an Anderson Power 
Pole model is also available for about $10 more.

The 4225 and 4245 both have front panel meters, plus a cigarette 
lighter socket in addition to the other connectors. They are 25 and 45 
amps respectively.

All of them also have spring loaded speaker type connectors for low 
current applications. These connectors are rated at a maximum of 5 
amps.

There is also a 15 amp MFJ model for about $60.

As someone said, that 15 amp model will run the TMV71 just fine at 
full power, but it won't leave you any wiggle room.

A 25 amp supply should run a 100 watt HF rig full tilt on anything 
other than a continuous duty mode like FM or RTTY.

A 45 amp model will very likely handle anything most of us would ever 
throw at it other than a solid state amplifier.
