What did you use for filtering the 12vdc when using the switcher units instead of the halo? I must have missed it and I can't seem ti mind it in that pile of posts below. Thanks.

Glad to hear everything is working as it should, Vinnie. Let us know what you decide regarding comparative sound quality.I haven't used the DC supplies yet. My order wasn't handled correctly, so I reordered a pair of the 5A switchers from someone else just last night.
You probably already know this, but just to be clear, I have two different uses for the DC switchers. The first is to generate 12VDC efficiently for 12V IDHT tube filaments, and to step that down to 6V with either a buck converter or linear regulator when 6V tubes are used. I won't know whether this application will require additional filtering until I test it with tubes. The second use is to tap into the square wave of the output transformer as a source of ultrasonic heating, in which case the DC output won't be used. The DC components will be left intact though, in order to allow the supply to regulate. This won't require any additional filtering, unless I decide to convert the square wave into sine.

Well, that probably explains why I couldn't find your post : ). Please let use know when you get them and start working with them. I would really like to know if you end up using a filter system, and what it is if you do.
I will also be curious to see which way you end up going for heating filaments for transmitting tubes as I am starting to lean toward the switcher units for their ease of implementation and the fact that they sound very close to AC when set up right.
