Vortexion CBL 6

"However I found the connection to both the mains and output transformers were open circuit on the important left hand amplifier. "
Isn't there just one mains transformer to power both channels or is there one mains tfmr per channel? Re the OPT any cheap and cheerful EL84 SE OPT should do the job. Unless you want to use it as a" portable" R2R* it doesn't really matter (ish)  if it is kaput as it's only there for the internal speaker, you should still be able to get a stereo out signal from the "monitor" jack and use this as an IP for a stereo amp/monitor setup or hifi.

I find it incredible that 50/60's recorders of folk music etc used to lug  R2R's like this on & off trains and walk miles to record people singing old songs in remote countryside. I struggle getting mine downstairs & onto the bench.

The CBL models are built as two mono chassis in a single case and have twin everything right down to separate mains switches for L and R sides.  The deck motors are switched from the left side only and the machine will operate with the right side switched off entirely; as a mono half-track set only, of course.

Clearly, Vortexion built it this for economy of design as the CBL shares chassis parts with the mono models albeit with some items made in a mirror image.  The circuit diagram shows just one half, plus deck wiring.

These are seriously heavy machines and the CBL carry handle is a masterpiece in engineering for the weight its designed to support.

Votexion made 'WVA' and 'WVB' models and the early stereo machine was 'WVC'. I've assumed that 'WVA' stood for 'Wearite Vortexion Model 'A', etc. However, where did 'CBL' come from, does anybody know?
