Which phones?bjackson said:I need a stepup transformer for some ESL headphone I bought.
Anything that would have a good 20-20khz response and not cost too much. Power rating isn't really that necissary.
Any ideas?
John Broskie of Tubecad did one for STAX cans in 2001 and there are a couple of designs by Kevin Gilmore on Headwize.
No knowledge or experience of the Beyers sorry. Apart from a breif period with a set of Sennheiser electros in the early 80's I've owned and used STAX's since my SR44's in about 1980. Mainly lambda Pros and currently SR404.bjackson said:They are Beyer Dynamic ET1000's. I bought them off of ebay as is, and I am really hoping that they are working! LOL.
When I get them in what is the first thing I should check to see if they are?
It is terminated with a 5 pin XLR.
Have you contacted Beyer to see if they can be of any help with pinouts, bias voltages or schematics of previous drivers?
