Title: transformer mistake and gift to me
Post by: copachino on January 08, 2015, 02:10:33 PM
I have a friend who had a eggnater renegate amp bit another friend told him he have a tourmaster amp that he could chance it because ir had a bad transformer PT it waa common those transformer to blow. I told him if you want get the PT and i will replace ir for you , so he bought a mercury transformer and yesterday i start todo replace it when i turn ir on ir dindt work out.... So i meassure original PT and it das good so i look better and see that there was no voltage on the input and when i saw there wasnt a part on the plug.... So the whole amp only needed a fusile replace.... What a fool thing i just dindt check it before cos the last owner said he was sure ir was The PT...

The good its The amp has a new mercurio transformer and since today its my birthday my friend gave me the original 100w PT.... So its great todo source parts for an amp

315-0-315 HT could be good for example for a Bassman type/JTM 45 solid state rectified amp (B+ will be higher through solid state than through tube rectification as you don't have a 5V rectifier tube tap anyway); you would have a B+ of about 430 V or so with solid state recto.
The 18V tap on transformer could be for some relay switching powersupply maybe and you could just ignore / tape that up unused.
Nice score.
