Mr.Nice

Early Celestion OT's need help to identifie I have 2 Celestion output transformers   they were used in Johnson amplifiers made in   Brandon Manitoba Canada. They are for use   with a pair of 6L6's but I don't know what   the secondary impedance is.I do know that   the 16 ohm version is numbered 4315   and the two I have- numbered 4400   4176   Does anyone have any data to help identify   these. I don"t have access to the 16 ohm one   if I did I could put an input and calculate   the turns ratio

Richie	I don't know if this will help, but is a great site for about every UK transformer company there is. If you still can't find it, you might e-mail one of them to get the answer your looking for.Everyone might like to lok at this.You'll find Drake, Dagnall,Radiospares,etc...   HTTP://www.applegate.co.uk/elec/pselect/ps_66.html   [Richie]

Book Of The Day

The Ultimate Tone, Volume III by Kevin O'Connor Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self. Note: The Ampage Archive is an Amazon Associate site. A small commission is paid to the site owner on any qualified purchase made after clicking an associate link such as the one above.

Doc	If none of the other leads get you the answer, you might check with Hammond. Apparently, they built transformers for a lot of canadian OEMs. (For instance, they built transformers for Traynor.) Ask them if they manufactured transformers for that amp company. If they did, they may have records indicating the characteristics, based on your part numbers.
