AMI ROWE Romantica - Spare Part Request - Bulbs in Circuit

Hello

looking for a spare part in the pre amp circuit from a 50W Amp.
On the circuit Board it is marked with DS1 / DS2
It´s a bulb which is soldered in.
The bulb & the zener Diode CR11 prevent damage to the circuit if excessive voltage is applied to the volume control.

One feet on the bulb is broken directly to the glass & I need to replace it.
Where I can buy this to repair the amp?

Can´t get contact to Alan Hood because the e-mail does not work.

Best regards,
Joshua

Dear Joshua,

Unfortuantely the schematic and parts list don't name this lamp other than DS1 and DS2.

I am not 100% sure, but I think it is GE#1764 having 28V 40 mA.
It is a very small wire terminal lamp and for sure used in models R84 to R-86 - and probably in RI-4 & RI-5 too.

I attach a picture of it.

If you look online for shops in UK (?) I guess you can find it. If not let me know.

We also fail getting in touch with Alan Hood for quite some time now and haven't heard nor read anything from him that long too. This might not be a good sign ...


Kind regards - Hildegard
