Re: help replacing an old ac power transformer.

I read in sci.electronics.design that John Popelish <jpopelish@xxxxxxxx> wrote (in <mIqdnfioLskT7dTeRVn-qQ@xxxxxxxxxxxx>) about 'help replacing an old ac power transformer.', on Sun, 9 Oct 2005:

Unfortunately, 24, 25 and 28 volt transformers are all more common. 

28 V plus a 0.33 ohm. Perhaps Watson would wind him one. (;-)

Buzzing does suggest shorted turns. Maybe the lamp is shorted. Does it buzz if you take out the lamp and then switch on? Does the transformer rapidly get hot?
