Well that bugger is now sorted!, Dam i just jinxed it lol :-D I missed the stream but you had plenty of people :-D I was starting to think there was a poor fit between a relay tang and socket receiver. Mechanical joints always play up.

Love BGW’s ! Weak relay coil, what an odd one.

Hey Dave, I'm currently running a Crown XTI - 4002 amp in my stereo setup and man this bad boy has balls - I have it running on 680 watts of RMS power into 8 ohms in Stereo mode. In mono bridge mode its up to 1650 watts of power into 8 ohms I think, I'm guessing at the moment without looking up the specs on Google. What I want to know is how does my amp rank up against that BGW 750 amp? I read somewhere on the net this BWG 750 amp drive the sub woofers in movie theaters back in 1974 to support the sound effects for the motion picture titled " Earthquake " starting Charleston Heston and George Kennedy. Do you have anymore insights about this? Great video btw....

Yes the bgw was designed and built for earthquake to drive the subs and shake the seats. A friend of mine dad ran movie theaters back in 70s and the studios brouhhyt all this crap in for the movie and the theatre owners took it all out after the movie and put it in storage. My buddy ended up with about 40 of these amps that had been stored in an unheated shed. Most of them were hauled away to the dump because nobody wanted them.

@@12voltvids okay...but how does this amp rank up against my Crown XTI - 4002 amp?

[@12voltvids]

@@lox_501 the bgw us rated only 250 per channel onto 8 ohms. It will do 750 in bridged mode into 4 ohms if i remember. I have a crest vs900 which will do 450 per channel into 4 ohms and 1200 in brigdes into 2 ohms 900 into 4 in bridged. It can shake the windows nicely.

@@lox_501 don't know anything about the crown.

[@markmarkofkane8167]

I'd like to see the speakers. That's a lot of power. Very interesting. My cheap combo unit says "700 watts" . But only draws 80 watts max from the AC source. That does not make sense.

[@12voltvids]

So it's 30 watts per channel

brian gary wachner made amps that NEVER EXCEEDED THE SOA SAFE OPERATING AREA of the devices.... thus never blew compared to the crown DC300 whcih blew and took out all the speakers../ bill ex JBL PRO & BGW representative back in the 80s..... and the crowns blew out many JBLs

[@12voltvids]

The crown amps were designed for scientific applications. They can go right to DC. No protection whatsoever. You would never catch me running my speakers on a crown.
