Sources in the Philippines / Manila

SwedishWings · 20th September 2006, 04:24 PM

Hope someone local can help me out...

I'm looking for a company in Manila that makes resonable good transformers.

1) From what I heard, there is no good source for OPT, but I can imagine that there are some who can make power transformers. Any sugestions on sources?

2) If there is someone who catually can make OPT, I would be very happy. I'm primary looking for guitarr OPT. Suggestions most welcome.

3) Are there any sources for tube hardware, i.e. tube sockets, solder support etc?

4) Tubes? I've found a few stores selling "guitarr amp tubes", but it would be nice to find more sources, perhaps with NOS tubes.

For the record: I've been building custom studio gear and custom amplifiers in Sweden for many years, and are thinking of putting up a "limited factory" to supply the European market with tube based gear.

Shipping from Korea and China should not be a big issue in Manila.
I'd look at Belton (Korea) for sockets, and reverb tanks.

Tubes purchased in bulk from the usual suspects.

ASL and many others oem transformers in HK and on the mainland.

Building guitar output transformers is an art, by the time a local vendor figures out how to build one with the right characteristics you would have been better off buying off the shelf or working with a vendor that already knows how to make output transformers.

Hifi transformer vendors generally can make good guitar opts with a little practice, but need to experiment with designing transformers with cheaper core materials, lower primary inductance, higher leakage inductance, primary and secondary dcr in order to get the saturation characteristics and tone sought for good guitar opts. Sometimes designing for deliberate winding resonances is useful as well. Given the abuse likely winding/interwinding insulation generally should be upgraded.

Oddly enough it is pretty funny that early Fender amps just used really cheap opts and got the right sound... more or less by accident. (And set the standard by which many others are judged.)

As for material selection in OPT and overall design in the early years... Yes, most of what we today appreciate as "the right guitar sound" is due to past cost savings and, i think, in much, lack of resources. The early Marshalls (like the JTM's from the 60) are mostly "custom designs", where they through in pretty much anything that was laying around on the shelfs. What happened then has influenced a couple of generations. If we predict the future on historic events - God help us

When it comes to importing stuff to the Philippines... well I could write a few pages on the subject, but let me just say that this is the second most corrupt country in Asia. If I could find a local source, it would a lot easier. Unfortunately your right again, by the time they got it right I'll be far to old.

Still, I'm an optimist, hoping to find some guys who can help me out... Anyone?

I have ordered Parts from Angela.com on several occasions and have no isses with delivery (if that's where your corruption thing comes off) right into my office.

My friend always order from Brian Cherry of DIYHiFi Supply and have no issues with shipping too.

I do however have an issue with TNT Express which is used by Eichmann Technologies in Australia. I despise TNT...

There are a couple of winders here, but your problem will be the source of the cores. My winder uses surplus cores from the U.S. and for PSU and chokes, I don't complain. I've had him make a couple of OPTs for me too.

Anyway, get in touch with Edrel Sison at the forum previously mentioned. He has a facility that does work as a sub-contractor for Emerson. I'm using his PP OPT prototypes right now and they're great, but probably not cheap as you want it to be. BTW, he's using what he called Z-core

I was reffering to the last container i brought in from Europe. The custom and custom brokers is not really working by the book... Anyway, I think you gave me a good advice here: use DHL and similar. Btw, can you recomend some particular delivery company?

Would you mind sharing your contacts? If they already have some experience, it would be of great help!

djQUAN · 21st September 2006, 10:26 AM

are there any other stores in raon you might want me to have a look? I'm looking for good sources of big heatsinks, some tubes and other hard to find stuff.

usually, I find them in sidewalk vendors getting a lot of parts some are new for cheap.
