A second word of warning is their mounting ears are shite
Alan, really I have used not as many as you have :D but a few and never thought that there was an issue with the mounting ears? But yes they do offer the stiffeners.

As much as I like Edcor trannies their mouting is very thin.

I must not be pushing the plates enough on my MC trannies because they get no more warmer then my Heyboers do which isn't hot.

Yeah it's kind of strange.

Yesterday while playing, I had the volume and master both around 10:00.

Then I use the Dumbleator output pot to control the actual volume I hear.

I was surprised at how warm the PT got.

Of course MC won't fess up but I think the only reason it would get warm is because it is a bit low in the specs for the current handling.

Maybe they use thinner gauge wire than they should, I don't know but heat is usually a by product of under engineering.

You can bend them with your fingers bro......many have come out of the box bent. But they do at least hammer back real easy.
Their 100W EL34 PT gets pretty hot.

I use big washers to stiffen up the weak legs on transformers. I haven't had a problem with cheaper legs bending when doing this.

It's not a problem that the PT will fail, it's the heat it generates radiating on other things that affect the tone. PT's can run way hotter than you could bear to touch and they will still be fine......it just doesn't give you that warm fuzzy feeling.

Is that a good thing? :D

Lets be honest, it not just these guys. Nearly all transformer companies supply with 'thinner than they should' be feet.

How do you determine whats "thinner than should be"? Who's a mechanical engr here?

Alan,

If they can be bent with your fingers then that is too thin, your correct. :)

I will have to check that out, probably I didn't even notice that when I mounted them on the chassis. But I use washers on all my transformers which is always a good standard practice.

The heat the tubes gives out worries more than the iron. :P

Oh yeah I wasn't trying to point at Mag Comp in any way. One of my friends had a Phaez (sp?) amp shipped from his house in NY to Florida and by the time it got there, the Edcor iron had completely bent away from the chassis. The iron was still usable and it probably got dropped by USPS, but this shouldn't ever be an issue. The amp I shipped from Texas to New York got there fine.

Mr. C.M.N Sense BSc (ME) Hons has determined it's too thin.

The PT I ordered off of Allied came looking like that with the feet all bent up. I don't really care though, I just bend 'em back and plop it in the amp.

I guess my point is......if you look at a stock transformer that comes from the Far East thats fitted to say a Peavey, they are actually much stronger and have thick strips of metal about 1/8" welded across each side and reinforcing the mounting ears. The chassis would bend before the transformers shifted. If they can do it, why can't the US transformer manufacturers do it? Just a pet peeve I guess.

When I was a quality control inspector (SCUBA industry), I suggested a $0.05 modification to a product that sold for several hundred dollars and was told that the upgrade would have a negative impact on the price point. Never mind that it would have saved several hundred units of returns but, hey, I was just the QC guy...

The last two posts by '67_Pexi and Zippy made me think. I have often thought transformer "brackets" seemed kind of thin/cheap. I felt this way about several different brands. As you guys have said, it seems kind of silly. I would be happy to pay another 10 dollars for a stronger surround. Even if it is just for peace of mind.
And like with all products, when there is a problem in one area, it does make you wonder about the rest of the device....
Thanks
