At 250v. O/P and full load, hum and noise level is less than 10 mV.
The HT O/P is floating w.r.t. chassis.

Note. The design is fairly simple and assy. is quite straight-forward. Should anyone wish to copy the cct. to build one on these, please contact me first for the cct. and various assy. notes.

The Paramount Cinetecnik 25 what mono block amplifier.
These have been restored and converted for vintage Hi-Fi use.
There is plenty of heavy iron on each cast alloy chassis and once restored the windows shake to the rhythm especially if we put Thin Lizzy on.

I have an 830/7 in very nice condition together with its original box. It is in working condition and I would like to sell it.
Perhaps unfortunately for this I live in Boston MA
