I am beginning to think I will just stay with the dc switching supply on the 26. It is fairly small and easy to adjust for the right voltage with just a couple of resistors and the adjustment screw. I can get a good measurement of the voltage and I can get it very close to the 1.5vdc I need. The halo is giving me a hard time as I have no way of accurately measuring the output as far as I can tell. Been trying to adjust it with resistors but it seems to very sensitive to the value. Just a few tenths of an ohm can make it go from working to not working, and with no way of measuring the output I am reluctant to waste 26's trying to see if it is right. Oh well, I got close and it only cost a few bucks to try it out. If anyone else figures out a way to use them for under 2 vac please post your method.

Vinnie, the halogen transformer won't work if you remove the number of output turns necessary to theoretically produce 1.5V. Two of us did that test at two different times, less than two months ago, and I thought you were involved in at least one round of those discussions here on the forum.
I'll also go on record again to say that no one should apply high frequency AC of this type to driver or preamp stages. The possibility that residual energy will be amplified and mixed in subsequent stages cannot be ignored if the goal is high fidelity sound.

Buy Chinese. Bury freedom.
Sounds like the dc transformer is the way to go then. Thanks.
