Default "Pertrix" grid bias battery label scans

Gents,

For those of you who might be wishing to re-label something resembling a grid bias battery in an old set, please find the scans attached!

Note that these are very much reduced in size; if you'd like the original scans, which are at 600dpi resolution, PM me and I'll send them through.

Cheers

Andy

Very nice. Is it 9V only or are there taps? What are the dimensions?

There were several taps on the original battery, can't quite remember them all (the battery was disposed of; it was a leaky mess!) but think there might have been taps for 1.5, 3, 4.5, 7 and 9v.

Dimensions were approx 12cm wide by 7cm tall, and about 1.5 cm thick.

I found it when I took the back off a very early valve set (pic attached) that I recovered from a manor house in Lincs, about 20 years ago!

Not likely to be a 7 volt tap . 6 & 7.5 would be possible, though.
