Dumbleator Transformer?

Post by TimDude »

I'm thinking about building a dumbleator. I'm having a hard time finding much information about transformers for this thing. From what I can gather in the pages on this forum specific to the Dumbleator is that the transformer is supposed to be 135V. I found these two transformers. I'm wondering if either of them would work.

I was thinking I would need to use half of the transformer, RED to RED/YEL to get close to the 135V.
Any feedback would be appreciated. If there's a different transformer I should be looking at, please let me know.

Thanks!

If you're not a stickler for voltages this transformer has 125v 15ma and 12v 0.3ma secondaries. If you trim the bobbin a little where the leads come over it fits inside a 1U rack. I've used it a few times and was pleased with the results.

It's a few bucks cheaper at CE Distribution if you are a dealer.

I'll consider this option too. Thanks!
