Will the ClassicTone 40-18066 be cool for a 5e3?
datasheet=> http://www.classictone.net/40-18066.pdf
I am interested in this transformer because its an upright mount. I am building a head with a recycled chassis and dont have a way to make a rectangle cut out.
The Voltages all look to be in range, it does have an added bias tap though, if i am not using this would i just not connect and cover the red/blue lead?
thanks a million for any info.

Re: Unused bias tap on power transformer
No problem with the unused bias tap. Cut the bare wire off, bend the end over a half inch, and put a piece of heat-shrink tubing over it. You have more rectifier filament current than you need (3A instead of 2), so the voltage might be a little high.
Re: Unused bias tap on power transformer
As for the rectifier filament current, is this a safe practice? or might i need to modify the circuit to accommodate the higher voltage?
Thanks for your time!! This is the first time i have had to look for a transformer that was not a direct replacement.

Re: Unused bias tap on power transformer
Filament voltage within 10% of spec is ok, so you may not have any real problem. You could ask MC what voltage you can expect at 2A.

cool, thanks guys!!!
