Title: Old Traynor Transformers in an OTS Kit? Post by: fishbookmark on March 25, 2012, 05:46:17 PM Hi All,
I'm new to the forum. For my 2nd amplifier build I will be ordering Package #1 The 50w OTS kit. I have an old Traynor YGL-3A Mark 3 that I'd like to use for parts. It has a very large PT and OT originally for a quad of EL34's and rated at 80w @ 4 ohms. Will it be a problem using these with two 6L6's? Will I have trouble matching to the correct voltage? Perhaps I should wait to use them with a JTM build. Title: Re: Old Traynor Transformers in an OTS Kit? Post by: SoundPerf on March 26, 2012, 03:04:48 AM I was trying to find a spec sheet for the transformer in question, but couldn't. As a drop in replacement, I have feeling it won't be as easy as that.
Do you know what the secondary voltages and current ratings are? I would need to know this information to make any kind of proper conclusion. Title: Re: Old Traynor Transformers in an OTS Kit?

You might try and find a schematic that will have the voltages on it.
The OT is probably a 1.6K-1.7KΩ:4Ω winding, which works out to 3.2KΩ:8Ω, not quite the optimal 4kΩ primary for a pair of 6L6GC's. Title: Re: Old Traynor Transformers in an OTS Kit?

Thanks again!

I forgot to get back to it. http://www.lynx.bc.ca/~jc/721020_YGL3_3A_Mk3.gif (http://www.lynx.bc.ca/~jc/721020_YGL3_3A_Mk3.gif) |
