Re: Dying Rectifier?

Cant find 2 off for 1k, but there is 9 off for 1k, still a bit optimistic. Looking a the ones that have actually sold £30-£35 seems more normal. But its just supply and demand in action. I think "Mullard" carries a lot of the weigh. Must have been taken down. But I agree, wishful thinking...

I've used used a modern 5U4, it was OK. It's directly heated cathodes.

Not recognising number 4 ?
I'm guessing drive-in movie speaker, hang extension inside the car. (?)

Re: Pye Sunrise Radio

Fab. Not jealous cat all. :D I guess originally there would have been a large paper driver and the case would be largely a U frame-type open baffle??? Bass cutoff would have been high, but it was a radio a century ago, and speech would presumably have been its sole role? Also to let the hot air out....

Re: Dying Rectifier?

Looks like the GZ33 was the guilty party. Incredible but true! :shock: I've just looked up GZ37 prices. Blimus! And I looked up the GZ33 data sheet. Mea culpa. Yes, a GZ37 is actually less hungry in heater current than a GZ37. I've just looked at eBay. 2 x NOS Mullard GZ33, original boxes, 'never u...

Re: Valve amplifier service

Before, the volume pot could only be turned a gnats, now it goes to 11 or 12 o'clock. Without a resistor divider to drop some of the signal. Does sound more managable and sensible, and is what I would prefer. :D I'm convinced the 20k : 100R can't be right. It's just nuts. :shock: Glad to hear it se...

Re: Dying Rectifier?

I did wonder if it's a bad joint or loose contact, so when you poke it with the meter probe, it works again for a bit.

Have you another rectifier to try? (Anything equiv to GZ33)

Have you done the unplug, spray with switch cleaner, re-plug in, check socket pins for loose fit, etc. (?)

Re: Nothing In Particular

Probably! :shock:

When my mum was in care there were intimations about possibly selling the bungalow to help fund it, BUT, because I was also resident there and over 60 (if only just), I couldn't be booted out so that it could be sold. :shock:
