I am using (2) split Bobbin type Power transformers for a Small Dual Mono Amp and i can put everything on one boare including the trans formers if thay can be placed side to side and about 1 inch apart. Any Ideas?

Try it
 
Hook up one transformer to the mains, put a voltmeter on the other and move them around. You will probably find that their relative orientation makes a big difference. Turn them around, place one sideways -- etc.

Have you considered detrimental effects of vibration on the rest of the circuitry? Perhaps placing them elsewhere for other reasons than magnetic will be worth considering?

Good luck.

Thanks. I bebated this for awhile But i Then could not be board mounted and i would then have to find another case other than the one i have on hand. But this might be A viable option. Because if board mounted thay will be Close to the Audio Circuitry also. However the Board mounted Method is sure Cleen.

ppl,

How about mounting the transformers in a different chassis and send ac directly to the amp chassis. This would avoid noise pickup and vibration problems. The bridge rectifiers and the filter caps could be mounted on the amp board.

Petter,

How is your progress on the back engineered X-1000?

Thanks for the Help. I placed the transformers in a mannor that thay would be used in and with no load or voltage on one and Just voltage apply to the othr transformer. I got about 30 MV of AC. so i amp going to have to find an alternative to Boardmounting these. Maby a separate case like wat was recomended above would work.
