WAD Transformer Numbers Help Please

[Richard]

We are seeking to help members with WAD amps who need replacement transformers.

To that end we need a list of the part numbers written on them. Many will be in the format "Dxxxx" often written in gold pen.

Can people please add the WAD amp model and Mains and Output Transformer Numbers to this thread when you're next inside your beasts!

Many thanks,
Richard

Hi Richard, that's for the newer supplier, Graham Luscombe isn't it?

Just for info. some of the older amps transformers were supplied by SP wound components?

Just to clarify, hope that's ok.

I am pretty sure that K5881, K5881 MkII, K5881 PSE, Original 300B PP and the K4WSE all had their transformers supplied by SP Wound. I do not believe there are any part number stamped on them.

However, Kit/Kat88 OP TX are stamped D8658.

Kit/Kat2A3 PSE

OPTX = 7525
Mains = 7473
Choke = 7474

Supplied by Morite Winding in Sandy, Beds.

just off topic, delete if ness., that 4 watt single ended, Neal, should be quite easy to do a diy, with the popularity of the loftin white, I am slightly suprised this is largely forgotten, shouldn't be dear to build, may even have a go myself.

Hi,

I've just sold a couple of the driver transformers for a PreII, as went over to CF! They were both marked "D8773" in gold pen, if that's any help!

Mike.

Just checked a Hi-Fi World from 95, The 4W single ended then cost £385. At the time K5881 cost £395, K5881PSE £650 and 300B £850 (without valves).

Hi all,
I am sure that all transformers with the black paper around the core and gold hand writing were made by Ripley Transformers of Ripley in Surrey, who I think are now part of a larger group on the south coast.
I think Richard wrote somewhere on the BB who they now are.

More info:

2A3 Optx - Design nr 7525 2A3PSE 2K/8R

300B PP Optx - Design7636 300BPP 6R O/P

These have cores wrapped in beige masking tape with white type labels and I believe were made by a company in or near Cambridge.

The ideal person to give us the info is of course Nick Lucas. I will see if i can persuade him to release the info.
