Default Problem locating power supply

Have a schematic for a 300B that shows the power transformer is from a Knight Stereo 30. Looking at the schematic best i can figure is

360 - 0 - 360
200 MA
10V @ 3
6.3 @ 6

I have not found any power transformers that have 10V @ 3

It appears that the 10V taps are unused. So why do you care?

OK, I have another ? Sorry I am very noob and trying to learn all I can.

In the schematic T3 is

5VCT 3A
6.3VAC 4A

So far I have found

Secondary: 275-0-275 V, 150 mA
Filament winding 1: 5 V, 3 A
Filament winding 2: 6.3 V, 5 A

With the second filament winding @ 5A is this an issue. If I am completely lost, just tell me, cause this 3rd transformer is confusing since I does not show like T2.

Thanks

As long as the transformer has the current rating higher than the schematic, you will be fine. Your selected transfomer will be fine.

dstockwell,

If funds allow, why not just have Heyboer wind a custom job to the specs you need.

http://www.heyboertransformers.com/

I'd hazard a guess it'll cost less than a hundred bucks, maybe even considerably less.

No down payment to start construction, after about 3 or 4 weeks you'll get the xfrmr and a day after that the bill.

Great folks to deal with, very patient and extraordinarily cooperative and the best customer service and money back guarantee of any company of any kind I've ever dealt with.

Plus they make some mighty good iron, some of the best out there.

Just food for thought is all,

Best,
mr mojo

Heyboer may have an "off the shelf" model that will meet your specs.

I agree with Mr Mojo. Heyboer is a great company. Their trannys are well-built and affordable.

Go to their website and look or e-mail them for help.
