Then after Acro's debacle, Allen was forced to produce their own OT, in house and from other company, often with rounded can. Some of you know my interest to the Acrosound family so I couldn't resist to try that one.īecause Acrosound's involvement in this project, the early model have the desired Acrosound monster OT in square can. The schematic looks very similar to the published TO350 amp from the Acrosound brochure, except the PS and the entry stage with additional tubes. It was mounted inside an organ and was design by Allen Organ and Acrosound. I wanted to share with you some work I did on this amps.Īs far as I know, this amp was produced from the beginning of the 60's to the 90's.
