Think he was selling it on ukvac some time ago

I think he is al or at least he was last year !

Is he still about(i remember him from years ago)

As Bob said above, max volume is approx 60 ohm, so you could put an 8 ohm in and change the 27 to a 49 ohm resistor, whatever you do if it is not original it will effect the volume but you can compensate by setting the volume to your required level, some have just put an 8 ohm in and not turned it up as much. There is an old thread here. Well done on getting to this stage and hopefuly there wont be any more previous owner errors to sort out.

andy keptboy has loads of it or he did ... might be worth messaging him ?

hello and welcome

Good evening. So, here's the report about the sound. All the sounds arrive on IC19 Pin 2 and exit on Pin 3. The normal playing noise is a 781 Hz square wave. The alarm is at 3.13 kHz. There's no signal on Pin 1 of IC19. It might not be used on my machine. Anyway, the sound works, because I had T11 reversed. The old boxes are reversed with the new ones. What goes wrong, goes wrong. (redo) . 🙄🙄 Regarding the tubes, I think there's a small problem; but I need to check their operation compared to the other machine. For the speaker, I found a 50 Ohm resistor. If I remove the 27 Ohm resistor and bridge it, will that work? https://composantelectronique.fr/haut-parleur/716-haut-parleur-philips-50-ohms.html Thanks for sharing your knowledge.

I will message you

Yes that would be great ,how do I pay?

I could send you both for £18 posted

Thanks might be worth a try ,how much is it?

I have no idea sorry! Also I have no way of testing them, pulled from a box of around 50 displays I have

Would rev A work mine is rev B ,thanks

Got a couple

One for sale here https://tinyurl.com/23wpo8bs Seems quite expensive though?

1. F3 on the fuse board 2. Unplug all the lamp plugs and reboot, if still alarms with lamps disconnected change MPU. You'll probably need this if you change the MPU BKBD611N9561253.zip

I've got a beaky blinders, one of the buttons the £1 was broken, now i'm getting a MUX col err 32 happening everytime I turn on the machine. It won't go past the error. Anyone any ideas?

Thanks that would be great

Will have a look tomorrow should have some

Good evening. Thank you so much for all the details.

I can't remember what the resistance is of the volume control pot but at maximum volume you will have approximately 60 Ohms load so half the power will be dissipated in the 27 Ohm resistor. I think the 10 Ohm is to stop the sound being turned off completely.

Hi everyone I looking for a display for Maygay epoch ,part no 16LF01UA4 rev B,if anyone has one for sale ,thanks in advance

Hello Thanks for the clarification, Bob. Your help is invaluable. I'll look into that. On another note, I have some questions about the volume control board. I've looked at the schematic and I see a 27-ohm resistor! It's original; not modified. Is this resistor related to the 30-ohm resistor of the speaker? And a photo of the series connection would be helpful. Thanks
