I like Bill's points.....however, I'd like to offer an alternative:
1. Do not buy a Ten tec power supply.
2. Do not buy any manufactured supply. They're too attractive looking.
3. Find a big ol' transformer that will supply 16v or so at 30+ amps.
4. Use some of the knowledge from that test you took and build a big,
ugly assed power supply with a 40A bridge and about 6 2n3771 pass transistors.
Place it under your desk. Hook it up to the rig with #8 house wire. Fuse the
PS, PRIOR To the crowbar circuit (see a book, any book)...at about 30A.
Fuse the RIG, if a T/T, at 15A (90w out--it'll hold, trust me--I use one every
day). Power all your other 13.8V junk off a homebrew (or MFJ) "13.8V power
strip"...
If you use big VHF amps it won't work, but then you're probably a "2M/440 tech"
and
don't read this group anyway.
5. Never buy another supply...buy all the radio junk you want...25 years later
(in my case--I hope to get at least another 30) you won't have to think about
power supplies, at all!!!
6. Use the $175 you saved to buy another radio, cigars, stereo gear, bicycle,
scotch,
hooker, or whatever you need at the moment...
7. If the radio hums, move either it or the supply around under the desk, or
alternatively
just drink the scotch you bought in step #6 until it doesn't bother you anymore.
73, Walt
