where do you buy those tranny covers? looks a lot like the ST70 opt trannies yes??
they are all from deeco! the power transformer as well as output traffos are from EI-150, the filter choke is EI-112. since the cores were from scrapples stampings, i just modded the covers to be used in an upright position as opposed to sideways! fyi, the legs for the ei 1.25 can be used for the ei-1.5 in an upright position! try this and you will see what i mean!;D
the output traffo, i asked a local shop to weld the legs to the cover shell since only two holes can be used. the corner holes do not jibe with the cover shells, sinauna kasi yung core na nakuha ko for the output traffo, that is why i had to improvise, the output traffo is a ei-1 1/2 inch core stacked to about 2 1/2 inch. there is no commercial equivalent for this traffo, ot has a primary impedance of 4.2k p2p to 4 8 and 16 ohm taps, i have even wound a separate feedback winding.
