Someone just purchased the lot of 3 for the 'Buy It Now' price of $19.93 each, and it wasn't me.

Could the Macrohenry Frequency Synthesizer be married to 12AV6/12CS6 broadcaster partly by stealing the Dale Saukerson power supply from the 6888 contest that uses the M.P.J.A. 27839 tranny with the secondary wired in series to get the 12v?

Well, either the Electronic Goldmine G12951 or the EPEC YS57H-110FA transformer will work with this transmitter. I wonder whom the suppliers were?

Absent these transformers, one alternative would be to just make up these xformers by hand (a project in itself).

What about this one?

This transformer on that site might work. It has 36VCT 750mA & 24VAC 2A secondaries.

I just happened to come across that transformer only 5 minutes ago.

I wasn't able to open the site but great. That's probably the same as we originally used. We tested them at the time and knew 36 volt winding wouldn't supply all the current that was originally specified.

There must be a lot of these transformers out there somewhere. I originally bought 100 and they had plenty more at the time. Since then Electronic Gold Mine sold out of the transformers. Tom made a transmitter around those voltages which aren't popular for most projects.

The link is operational now.

Nice transformer and price, $3.99. Order 100 and only $3.00. Probably the same as we used. Coming from Canada will add some expense to builders in the US.

I'll cross my fingers, and hope that they actually have those in stock.

Should be quite a bit less with US to Canadian dollars???

They were out of stock when I checked yesterday

Hmmmm......I sent them an e-mail yesterday inquiring about the transformer, but I didn't receive a reply yet. This morning, I called them up at 514-376-1740, but the person I talked to only spoke French. Those people over there may only speak French. I wonder how the other ARF member came to find out that those transformers weren't in stock last Saturday evening?

Well, I just sent addison-electronique another e-mail, and this time it was written in French. All that I simply asked them was if those transformers were in stock. Now I'll have to wait for their reply.

The website shows that they are out of stock

It didn't show that on the site page which I was on, but evidently they are out of stock. Thanks.

I found it when I searched for the product. I searched because they didn't have a way to buy it listed.

Thanks for all the efforts to solve the iron problem on this parts kit. I'm sitting on the small parts inventory just in case we find a tranny at some point. This was a very popular parts kit for AM broadcasters of the 6888 type.

Looks like I'm very late to this party. I'm looking to build an AM transmitter to test my radios, preferable an 'old school' tube transmitter to fit the theme. This is a very long thread with twists and turns along the way. Is there a Kit that I can purchase from someone or could someone point me to the latest and greatest parts list and schematic? Looks like in the end there is an issue in getting some of the necessary parts....Thanks!
