Default Car audio SMPS transformers

I have many SMPS transformer "pot cores" from my car amplifier building days. These particular cores are made by "magnetics" part#OF44229, they are an equivelent to the "Ferroxcube" 3622PL00-3C8. Good for about 250 watts continuous (about 125-150 audio amplifier watts). Each transformer contains two cores (top and bottom), you will need to make a plastic or cardboard former to wind your coil on, as I am all out of formers for these size cores. The price is $10.00 US, shipping is included in the price. The cost will be more if you need shipping outside the US. I will also include (free) a copy of the Audio Amateur (four/88) article for building a power supply (SG2535 based) with the schematic and parts lists. I will also include 18ga magnet wire to wind the cores with. The cores are new, never used. I reserve the right to retract the "free" copy of the article if I'm in copyright violation. Anyone know?

how many do you have?

I'm definately interested in somewhere between 4 and 8.

Think I could get a bulk discount if you have that many?

Okay... Digging up old thread here, but are these still around? I've been going nuts looking for ferrite pot cores, and these look like just the ticket.
