Loved those old BK Electronics amps. Simple, reliable and built like the proverbial brick shithouse.

Well....i have good news...bad news and some betwin them
The good news,i have Matched Hitachi's by H H Electronics removed 10 years ago from an V800 (driver board was totally rosted,i made it to work but i didn't like the way it looked so i made it for parts. The bad news,i know for sure i have three pairs of them..but i only find two pairs (that's because i have 150 boxes with parts and spares and god know what more because i always travel from UK to Romania and back) but i will find the other pair for sure,all the rest of them are running in other mosfet amps for years. And betwin bad and good is the fact that i'm currently in Romania now,and to send them from here will cost a lot and will take forever to get to you,but next month i'll be back in UK (London) and i can send them to you via Royal Mail 1St. Here a photo of them:  Cheers

Jack Sondermeyer is the founder of the design. He sold the design to Peavey and BGW. Hartley Peavey was so impressed with the design, he hired Jack to make their amplifiers. Below are Jack Sondermeyer's Patents. Jack worked for RCA before moving to Peavey.

The outputs in my BGW 750B the Motorola ones are SJ-s i guess peavey's mark,i don't know if this amplifier comes with this mix or has been repaired before
 obviously the fresh thermal paste is my job    Edited by EmPro - 14 January 2023 at 6:53pm |

Indeed i have the last generation of CS800c 4U before they moved to 3u and tottaly different output stage,i didn't have the luck to find the first ones without the DTT limiter and RCA-s outputs,i bet those are even stronger then this one,however i do have a BGW 750B with RCA-s inside and Motorola's npn and pnp that push the same amount of power as this C800c in the same frequency range,also running better in low's.

Peavey purposely underrated their amplifiers at that time. Their were many that felt Peavey amplifiers did not meet their specs. It was based purely on bias hatred towards Peavey. I own a good amount of CS 800s (yours is the last series before they downsized to the 3- Rack version). If you ever happen to find their first series (No DDT and will say Overload above the LED Indicators) you will find RCA TO-3's on the heat sinks. The first series also weighs more than the model you posses. And yes, for Bass, Peavey Amplifiers are not shy playing very low frequencies. My second choice for a sub-low Bass Amplifier (First being Crown).
Best Regards,
