I'm looking for more info on the set below; particularly schematic and hardware.
Columbus radio (RCNZ) 6-valve model 032M (note suffix not ‘N’)
B.C. band only, 4 controls: volume, A.C. sw, Tone, Tuning
As received valve line-up: miniature 6X4, 6AQ5, 6AV6, 6BA6, 6BE6, 6BA6
No physical reference to actual valve line-up so It’s possible those in place are not correct
Serial No.: 14821, Pressed chassis, Phono jack at rear
This set appears similar to Columbus Model 5 miniature-valve but with some differences;
Additional 2nd stage R.F. amp (hence 6BA6 x 2) so 6-valve, not 5-valve
6X4 rectifier instead of 6X5
6AQ5 output
