Looking for any info on a 67? (based on your sn# chart), 4 channel PA Head model #1145PA I aquired about 20 years ago played through awhile and stashed. I ran accoss it again and found this site (great site by the way!) I didn't see any info on the site for this model and was wondering if anyone knew the spec's for it and what the extra jacks on the back are for. 2 1/4" went to speakers but there is an rca I'm assuming went to a mixer? and another 1/4" jack I'm not sure of? Any info would be appreciated.

The 1145PA is listed in the 67 catalog in the literature section. It originally came with two speaker cabinets, each one containing 2-15" Jensens and a 15" high freq. horn. The head is a 200A series "energizer", which is sort of a cross between the earlier Frankenstein heads and the much more common 200B series heads. It is rated at 100 watts RMS and as you know, has 4 channel and reverb.

Besides the two speaker jacks, there is an RCA jack that is used as an output to either another amp, for more power or to a tape recorder input, and a 1/4" jack that works with a standard foot switch to turn on and off the reverb.

All this for a mere $1,145.00! The earlier series Frankenstein amp model numbers were all based on the list prices and speaker brands. In the A-series amps, only the PA's continued with this system.

Out of curiosity, does your head have the two push button circuit breakers on the front panel?

Thanks for the info. As to your questions, I'm not in front of the unit. I don't remember any but it must have something for protection but I'm pretty sure it' not on the front? When I got the unit ('83?) it had 1 bad channel that I replaced a transistor on and used for a couple of gigs for a church youth group and then stashed in the closet. Ran accross it the other day and may resurect it with a couple of cabinets.

I checked out the amp and there are no circuit breakers on either the front panel or the back panel. I would assume that it must be fused inside.

If I were to order the schematics here on the site which would be the closest since the 1145 is kind of a cross?

There probably is a hard wired 3A power fuse on the inside of your amp, that replaced one of the circuit breakers that was mounted on the front panel in the earlier A-series amps.

There are no known official A-series schematics out there as of yet. I know that a few of the guys here have found that one of the other model schematics seems to be very close to the A-series boards. I want to say that it's the model 400 PA, but don't trust my memory and put up a separate post looking for an A-series schematic. One of the other guys here will chime in and let you know what to look for.
