I found this on my late parents attic and thought I’d list on here before dropping it in the bin

I have no idea if it still works or not

I’m sure I remember my father using this on a reel to reel tape recorder 50 plus years ago but could be wrong

Base is marked

Type EL3766/00

50 Hz 10W

I think it’s Grundig

Selling for spares or repair

Shame to bin it !
