where to buy parts (transformers and chokes)
 
i am building a tube amp for a college project,,
consequently time is of the essence.
i have found sources for most components, but i cant find a decent supplier of transformers and chokes for valve amps.

if any of you know of any decent suppliers of tube amp parts (preferably as close to the uk as possible) please let me know.

cheers

Hello soundbadger,

I have had great success w/ Electra-Print iron. I believe the quality is second to none, and you get the added bonus of a transformer tutorial when you get Jack Elliano on the phone. If you're not exactly sure what you need, he'll even figure out what's best for your application. Sharp guy, very helpful, and a superb product. I know Las Vegas isn't close to England, but with the pound/dollar ratio what it is, the prices should be very favorable.

Good luck w/ your project.

Cheers, Crazy Bill :)

In the UK, S&B transformers are a local supplier. They are a bit spendy though. Then there is Lundahl (of denmark). James, Hammond, Tango & Tamura are other names that comes to mind (3 of 4 of those are Japanese made).

Sowter are in Ipswich.

Sorry, knew it was Scandanavia, guess I was mixing it with speaker driver manuf's of note.

Hi !
I know nearly all output-transformer-dudes on the planet.

In the UK there are:


Majestic Transformer

Living-in-the-past

Sowter

Variable Voltage Technology

HIFI Collective (Glasshouse & Audio-Note Transformers)


Think that was all.

I Hope I could help you

Regards, Simon

PS: Du to that low $$$ it is a very good chance to buy in the USA. One Pound ~ 2$ ! You will get these Hammonds and Edcors dirt cheap !

Edcor will also custom design something for you too, at a cost of an extra 20USD NRE, which is a great deal i think. Nice people to talk with on the phone too.

power supply PLEASE HELP
 
hello there
i have designed a power supply using psud2 (see attached jpg) , it is to power 2 kt88 tubes and 2 pre-amp tubes (undecided on exact type), i just wondered if someone could take a look and tell me what they think. is there anything i should do differently. i need a power supply to give 2 different voltages for the power and preamp tubes this seemed the easiest way.

the transformer resistance of 150r is just a guess but the chokes 82r is a hammond 193j.

any help appreciated,,,,
