Pye R33

[Yorkie]

Speakers are far easier to come by than complete R33s

Don't bet on it! I haven't found one in two years of looking. I haven't even been able to find anything which would 'do at a pinch' - a round one I could mount on a baffle-board or even an 8Ω one I could stick a resistor across.

You're sorted then!

The R33 ssed a 6” x 4” 3 Ohm elliptical speaker. 6” x 4” (and 5” x 3”) elliptical speakers are available in abundance, though generally only 8 Ohm but as you say Joe, that's not insurmountable. However, 4 Ohm ones can also be had, but generally in pairs for use in car stereos. These for example at £12.00 a pair, (Buy it Now) but the killer punch is the £7.50 delivery charge:

I would have though that local car spares outfits would perhaps have them.

6 x 4” speakers were very commonplace in TVs and I can’t begin to imagine how many have been skipped over the last four decades.

Hope that helps a bit Joe.
