Check, but as far as I am aware the 780 don't do bridge due to psu limitations

Quite an expensive amp to blow up trying!

Will the epc 780(or 760) do 4r bridge into 2 subs running 40-121hz loaded with v18-1000?
epc780 does 1500w @ 2r per side, so 3000w into 4r bridge.

Firstly, that what i call a tower of power, reminds me of the problem of lugging Genie boxes up unsuitable stairwells in the late 70's.

Secondly, my email is pipahire@pipahire.plus.com

Any help is appreciated.

Thanks

These amps offer incredible savings on gym membership, though venues with narrow steep staircases even with the fittest of young men are best avoided.

Afternoon to everyone, just a "newbie" on here , but long in thr tooth otherwise.
I like to spend my "free time" fixing dead amps for the challenge of it, between lugging the working ones in ands out of gigs. So here's a plea fromthe heart, I've read up what i can on the EPC 780, I'd like to fix the one that was donated to me, any suggestions for where i might get technical info/circuit diagrams, or am i just wasting my time?

EPC 780 weighs 25kg, mostly contructed using 2mm and 1.45 steel plate. Power is 1000W 4Ohm, 1500W 2 Ohm - copper heat sinks with biscuit fans, MOSFET output stage (IRF740s I think). Dual switch mode power supplies, The EPC760 where optimised for high frequency reproduction.  The last few made left the BSS factory at Potters Bar around 1995. I modified at least a 100 as BSS still came up with fixes for problems up until aroung 1999. The guy aound is to repair and maintain these amp is George M of DBA based in Baldock, he is the ex BSS service engineer and has exensive knowledge of these amsp and has some spares whcih inlude graded MOSFETS. I really liked these amsp and owned a few, i thought these amps sounded great and mine never missed a beat - fitting the correct fan filter material helps keep em cool and these need washing out often!

Cheers  Dave
