well, the toroids arrived -- first rate quality and they test as per the specs given prior to the build. The toroids are finished with magnetic shielding tape and are potted. The label says 'Plitron/Salzer'.
As Navin said, always good to have another address which is diyer friendly.
By the way, anyone know where I could source air core inductors????? -- I need 4x 2.2mh 12/14awg coils for a Pass amp PSU filter..... so far haven't been able to find a place. I'm in delhi, but an address anywhere else in india would be great.

Many thanks for the help, and also to member JPS who mailed me off-list.
So I checked out Bhagirath place -- and found enamelled wire. Problem, however, was that in all the shops I checked the minimum purchase was 20kg
However I was given an address which sells in smaller quantities. It's on the opposite side of the road to the McDonalds and the entrance to the Bhagirath market.
Hari Singh
239/25 Kunjas Street (more like an alley)
Dariba (a street with jewellers)
ph: 2328 6190
They had a very good selection and sold me 4kgs of 14swg.
So I took Navin's suggestion and rolled my own. Not with a lathe, just a bolt and plates attached to an electric drill. Worked out OK -- good enough for a PSU choke, but if you;re planning nice speaker coils I'd do it properly
On another subject (and in the interest of keeping this thread updated with regards to addresses), I tracked down SPM Metalcraft in Lakshmi Nagar (they supposedly make racks/cases/chassis). However they've moved to Gujarat....
Now I'm trying to track down a metalworker with nice thick alluminium sheets....
Have yet to check out the Noida addresses Sumit kindly offered on this thread (metal workshops), though would welcome any other Delhi chassis suggestions.

14SWG is about as thinck as you can roll well using the technique you used. Once you get to thicker wire a small lathe is really nice to have.

You could try Corrson electronics www.corrson.com at Bangalore. They can make you custom inductors. I just used a set of them for my speaker crossovers.

Re: Latest Miracle toroid prices..........
Miracle claims this is due to increases in copper prices over the past year. Parts Express probably sources it from China in bulk.
ashok said:Anyone bought toroidal transformers from Miracle lately ?
I bought a few and find their prices are higher than Avel Lindberg from Parts Express !
New development ? Who else make toroids to order over here ?

I have been following this post for some time now. Some of you guys are from Mumbai and seem to have built your own tube amplifiers.
I am in the process of building a Class A tube amp myself. Can someone help me with this...
