Mercury Magnetic JTM45-RI-P won’t fit.... Help.

I'm finding it hard to believe that you couldn't make it work. Maybe some drilling, maybe a trip to the hardware store for washers, etc. Looking at your numbers in the first post and the datasheet Mike so graciously posted, the transformer should cover the holes in the chassis. Nobody would see any "adapting" you'd have to do internally in order to securely mount it.

Why make enemies when you may be in the wrong.?.

In the meantime I’m going to call MM to ask what they where thinking when they made this particular model.

It is meant to fit the re-issue. I don't think the vintage size one will fit the re-ish.

Thanks to everyone. I will post some pictures when I get to my desktop computer. iOS forum doesn’t have an option to upload images. Transformer is a tad too small, so drilling new holes in not an option. I’ll probably re-use this chassis for a proper sized PT.

Some info anyway. Didn't think they had these all online.

got any photos you can post of the transformer and chassis?

Are the dimensions cut out size or location of the holes?. Anyway If your xformer is smaller, see if you can make it work using Fender Washers.

But, whatever else Mercury does, they usually clone accurate for mounting from what I've read. So the RI must use a different size transformer than an original, which is likely what the Metro chassis is cut for.

It's a clone, not an original. Even boutiquey type amps often have odd cutouts and plugs for correction. Drill new holes or, if necessary, add a mounting plate or something. I don't think it's great shakes unless you're OCD over it.?.

re-issue transformers are not always the same size as the originals. I suppose the metro is using the original size PT.

Can you just drill new holes? The transformer is upright or the laydown style?

this person can make a custom chassis for you but not sure if you need it all predrilled and pre cut

Hello everyone, got a situation here. I ordered a chassis for a jt45 build. I was going to use my Mercury Magnetics Axiom jtm45-ri-p Power Transformer (center to center 2-1/2 x 3-1/8”) but it’s too small. The holes on the chassis are 2-78 by 3-5/8 which I believe is the metro-amp standard chassis size. So my questions are: what gives?? Is this PT special? Can anyone recommend a chassis that would fit or do I have to do a custom chassis order for this PT? Thanks.
