I have the opportunity to buy several of these amps cheap. They are, however, ex rental gear so I assume they've had a long hard life. My thoughts are bridging a pair of them for monster amounts of power for the low end on my 4343's or other adventures such as triamping. Anyone had experience with these?
Thanks
I have a 250D & a 750D and really like them.
The "D" does put out more than a "C" , but the C is no slouch either'
and I understand hard to find down under.
They are very well built.

Thanks Seawolf will do, yeah I don't recall seeing bgw's very often here.Originally Posted by SEAWOLF97
I've been reading a lot about the BGW's and they seem to be perfectly suited for bass duty.
Do you have any chance to take a look at the internals before purchase to check for bulging caps / replaced transistors?
After you have renewed the psu caps, level pots and r&r'ed the tantalum bead capacitors with low esr electrolytic caps, you will find the vintage 750 b /c / d to be sonically suitable for most any use.
Just watch the volume control -- the prodigious current drive capabilities of the 750 b /c / d can easily fry most speakers.

Yeah I doubt I'll have the chance to do that but will try to take a look out for those things, good thinking.
Just picked these up, so I got 2 x 750C. So can bridge. Haven't fired them up yet, will post impressions and pictures when I get a chance. I also picked up another Perreaux 6000c to go with the 6000b I have so I definetley have enough power now
So I briefly fired these up last night. But before I could I had to make up an XLR cable with a hot pin 3 (That's how BGW rolls for some reason). I only had time to make up one cable so just listened to each channel at a time on each of the amps to make sure they were working. First impressions, they sound very nice. As Loach71 had said they sound a little tube like.
Looking forward to conducting some maintenance on these babies and getting them working well.
I just made up rca to 1/4 TRS cables for my 750D's ... my BGW 203 preamp uses rca's
The D model (unsure about the C) can use "pass thru/daisy chain" TRS. ie: signal goes into 750D and exits to my 250D. Can run one or the other or both amps from same 203.
Run them "wide open" (no attenuation) and no need to ever adjust knobs.
My D has a 2 speed fan ...high/low/off. Low didn't work and high was too loud. So I disabled it and mounted an external computer muffin 120v fan through a pot and tuned it's speed to just below audible noise. Amp runs only slightly warm and no problems.
Owners manual is on the web.

Thats a nice trick with the computer fan, might give that a go. Was gonna teflon spray the bearings first to see how quiet i can get it.

Uhm, AFAIK if you have pin 3 HOT gear you can just flip the speaker polarity without making any special pin 3 hot cables.
I was running Urei 6260's without any problems with standard XLR cabling.
