Not to answer for Paul, but it was the MP2510P4AS

Thanks!
Exiting setup. The race to replicate has begun

Ok, so it should be the 2714 material.
Looking at the specifications, I noticed that there are actually 4 forms:
- Anneal longitudinal field
- Anneal Transverse field
- No-field Anneal
- As cast

Looks like they have 3 different manufacturing methods.
How do I know what I order and what did you guys order w.r.t. the anneal characteristics?

As I've said earlier, I don't think there is much sense in the recycle circuit, as the metglas material has very high remanence value (about 0.5 T) comparing to BSAT which is 0.57T.

Hi Paul,

Been working on recycle circuit, have the run time on my turntable motor up to 3 1/2 hours with at least another 2-3 hours on my 650F BoostCap.  Not quite over but real close.  Started @ 2.000 VDC now down to 1.17 VDC after 3.5 hours.  It is difficult to match the loop current and boost it back into the cap but it can be done.  Your have a valid idea.

Hi Gang,

@ 5 hours, voltage is 0.879 down from 2.000 V with 650 F........go figure.  It is running down albeit very slowly.....But progress is being made.  Will stop it now, rebuild circuit with better transformer,  FWBR instead of 1/2 wave.  Then see what happens.  Might change to 10,000 maH nimH.....
