Sorry if I missed your post recommending this model of MOT? Looks like Guangdong Microwave Mfg in China is the leading OEM supplier of MOTs to many microwave oven manufacturers.
Would the 11vac audio on the primary be generating hundreds of volts on the secondaries, so we have to be careful not to touch or short the secondaries for fear of shock? These MOTs when loaded with 120VAC on the primary will smoke/zap you badly, or worse, if you touch the secondaries.
On a MOT, the primary is like 14ga wire and the secondaries are thin ~28ga wire with the HV tap grounded on one end.
An externally hosted image should be here but it was not working when we last tested it.
@ marconi,
the nichis are available here:
Elko, radial online kaufen | Pollin.de
30ct if you buy >100
they have a relatively high resistance (ca 1R)
regards

The current should divide by the same factor that the voltage multiplies, right? Still don't think I'd be interested in touching a secondary. Could be a couple hundred VAC at 0.1 amps using the 11VAC signal example above......

HI Meanman,
Can you tell me where you got your chokes from
"Choke specs 176mH/3A/rdc: 0,5 OHM"
many thanks

Afaik class A amps have a very constant current draw. No need for a fast PSU. And I use several. So you get a low effective ESR.
These Nichicons are Vz series. Not very new. I bought some two years ago and a new batch last month. Identical codes....
In my amp they don't heat up what so ever. Seem to behave fine.
I also got the Sikorels from here. Dirt cheap and new.

It looks like meanman have some sort of this smoorspoelen from AE.
Goede smoorspoelen koopt u bij Automatic Electric Europe
I will try the cheaper Hammonds with CLC Filtering- need a bit time more.
Regards.

Custom made by AE Transformers from Holland . Maybe you can ask Toroidy from Poland too
AE is well known for its tube related transformers. Nice and not very expensive. I didn't think of them as choke suppliers (but I see it is actually their core business).
Regarding Toroidy: on this forum is a topic about this company (tube section). And also on other forums this company can be found. They used to have the issue of providing non-usefull data. The inductance was measured without current and the maximum current had hardly any inductance left. With Hammond you have a rated current and rated inductance....
But I think Toroidy promised to improve this. I don't know the actual status.
A lot of Toroidy stuff can be bought from TME (also from Poland). Good supplier.
I paid some attention while powering up my amps. You can't hear a thing, but you can see.... 😀
The woofer cone is moving backwards while powering up and forward powering off (my woofer is out of phase). But this movement is small and slow. So you cannot hear it. Only see.
