Re: WAD Transformer Numbers Help Please
Hi Philip
Those figures sound right for K5881 then. That was EI and ran 360v with no centre tap onto a bridge for ht and powered the heaters of 4 el34 and the small valves. Rich |

Should be enough for my needs then. Has to run 2 off 6D22s,1 0ff 829b and a 6SN7-GT which is 5.25A,so thats a bit in "reserve".

Re: WAD Transformer Numbers Help Please
You may have a problem here. WD's Tx's were made by Morite. They went bust towards the end of last year which added to WD's problems.
Grant Armstrong, formally Morite now works for Amethyst. Have a look at the link below and click on the heading about Grant joining them. There is an email link for Grant himself. I understand he has all the Morite designs with him so might be able to help. http://www.amethyst-designs.co.uk/News/ Regards, Greg |

Re: WAD Transformer Numbers Help Please
WAD HD83 and WD HD3 output Tx's
Grandchain design No D8449. I believe that Graham Luscombe is the man you need to talk to about them. He is winding me 6 as I type..... The HD83 mains was wound by Morite in Torroidal style. Grant Armstrong at Amethyst put me onto Frank at another company I think are called SP wound or something like that, who have the design for the mains. I got Graham at Grandchain to wind me three uprated mains for a reasonable price into the bargain..... 165V@100mA and 3.15-0-315V@2A So a bit extra juice if you need it. Filed under D9403 Shame I have to wait a couple of weeks but it should be worth it....

Re: WAD Transformer Numbers Help Please
Just a quick update...
The Grandchain transformers have arrived, and are very very well put together. Delivery was way in advance of the agreed delivery date. Overall very happy with the service and price I received. Gone to do a lash up now........
