You can bring it to Martin Electronics. Search yellow pages for the exact location details and contact.
They are the official hammond dealer in Singapore for transformers and enclosures.
You can ask the aunty there to get a hammond replacement for you. Alternatively, you can get sweelee to order in for you a fender replacement part.
Or, you can order online a mercury magnetics replacement and get an amp tech; e.g Martin Electronics, to replace for you for a fee.

Oh btw, is it the power transformer or the output transformer that went?
You might want to get a tech to do maintenance on the amp as well since there may be underlying problems that caused either of the transformer to malfunction.
Best bet is to first call up a tech, describe your problem, and ask if they are able to order a replacement part and do servicing on the amp.
On the forums, I think goose may be able to help you. You can try PMing him. Good luck.

Is it a old Twin? If it is you should check out what exactly the amp is all about, the tubes, the power and preamps, the transformers it uses etc before doing any fixes. If its a newer one and the problem is easily traced you should again find out info on what parts to swap out of and what to replace them with.

Thanks. I already checked there when I went to SLT. They don't have the filter caps shown on the photo... I admit, I'm clueless about this stuff... I'm just trying to find exact replacements

You really should just send it to a tech. Amps are not the best things to tinker about with if you're not sure of what you're doing.
Not necessary to get exacts, get good quality ones with equal value.
The toasted ones look like
70mF 1000V
220mF 285V
Higher voltage ratings would be fine, not lower though.
Just ask the lady there for good quality replacements, ask her to recommend something that will suit it.
Maybe something along the lines of: " I got some filter caps that popped, these are the values, xxx , they're from an old amp, can you recommend me some NOS caps that are of these values. "
A better solution is to bring the unit down there for them or any qualified tube amp tech to look it over. From my experience, the family that operates martin electronics are genuinely interested in tube amps and audio and not out to make a quick buck. Their price lists are all open for everyone to see in their plastic folders.
You know when someone loves their work when they invite you to listen, chat and they don't need you to buy anything. They just want to share their knowledge with you. At times I just went in for chats, other times I picked up tubes for replacements. But always, they are available to answer your questions.
I can't say much about other amp techs in Singapore as I have no experience, but all my experiences with Martin have been favourable.

I agree. I spoke with the lady there and she was very helpful... I will pay their store another visit later.
My friend doing the amp also told me its ok to get higher voltage ratings.
20mF 500VDC
70mF 100VDC
220mF 285VDC
Thanks again

Hey the amp is fixed!
Turns out both power and output transformers were blown.. expensive fix man. I ordered the transformers from mercury magnetics.. cost me a total of about $600USD!
