Buying parts for me and other persons repairs are 2 different things. Hammond transformers are not cheap. For instance, their 50 Marshall drake copy (Hammond # 784-139) sells at Metro for $150.00. The cost me $108 each, but are $68 if I get 10. I love this OT and any I put in others amps, they love them as well. They tend to hold up much better than stock.
Weber sells Mercury Magnetics and cannot drop ship for some reason, but I have had one dropped shipped to me. I do not know why, but I believe thy hold orders to get a certain quantity to get a larger discount.
If I am purchasing anything for a build that I know I will keep, like the AC15 a couple of us have built, I get what I want. If I were looking for a deal I could just buy a used one for $400, but that is not why I build amps. I purchased a Mercury Magnetics and with discounts it cost $128.00 whereas the list is $235.00. Still high, but the tranny Sluckey and Lego used is about $108.00. Sure we could have gotten a Classictone, but I tried on several occations to confirm if it were 6K as the spec sheet states. Not a single reply from Magnetic Components, and their 2 dealers did not know.
Email Patrick at Mercury Magnetics and see how long it takes to get your answer. Usually within 30 minutes.
So if all the transformers were setting in front of you and you could get whichever one you want, what would it be? The bitter taste of poor quality lingers longer than the sweet taste of low price is forgotten.
Also, they do have a great selection and I can wait 6 weeks for Edcor, but if it is a repair, well that is a different story. I really do not think anyone buys a paint job, but they do buy hype. Edcor gets attention from the pretty paint too, but they do have good prices.
But I can afford another $55 to get what I want for an amp I plan to keep, but I also use George L cables on my pedal board because there is a noticeable difference and play nice Gibsons, Fenders and Ibanez guitars. If money was my main concern I wouldn't build amps and I can get a good guitar for $400.
I wonder how many people state an opinion that have never used Mercury Magnetics?
