where can I find 24V wheat lamps?

[Luke]

Hi guys,

I have an old Denon PRA-6000 preamp adn Im struggling to find a denon rep in NZ and order a service manual and parts.
however I have identified the dead lamps on the glass front panel as 24V wheat lamps with bare wires.
I have found 6,12 and 18 V wheat lamps on the net but not 24V?
Anyone have any idea on this and any of my other Denon parts dilemmas?

thankyou in advance.

Two 12V lamps in series?

Or a pair of nose-to-nose 11V zeners will get rid of 11.7V (assuming 24V AC supply, 24V DC just use a 12V zener or a 7812).

Checking a couple of UK catalogues all I see is a 28V wire-ended.

I had a similar dilemma, I needed the 12-15v equivalent, ultimately eBay was my friend. The model train enthusiasts seem to use the lower voltage versions and perhaps have the higher voltage as well...OTOH the 12v zener in series may be the easiest way to go...

If your 24v is ac, whats the average voltage you get from a simple rectifier in series with the bulb? 12v? this may be simplest of all...

thanks for your replies. I should take a photo, but a board with contracts has a cutout where a plastic bulb holder slots in and twists, The bare wires make contact with the pcb copper track and you get light:-)
Adding a zener or 12v reg would not work very well here due to space and there is no soldering that can be done here.
So I really need bare wired 24V wheat lamps.

I hope you'll find there what you need.

thanks for all your posts guys, but still not found the right one.
Sounds inc, I have looked at this one, but it has leads, I really need a bare wire, or it wont fit in the holder.

i would replace em all with
white LED and a resistor. use the "natural white" ones. you might need to rough the plastic if you can not find "diffuse" leds, seems more and more the waterclear are more commonly made.

for the resistor. just google "led resistor calculator" there are a few

If it HAS to be authentic you might want to look on some model railway or maybe dolls house forums. they might use something like that

Hmmm, sounds to me like it was worth a try to take one of them down to the local car repair. Ask if you can have a look at his drawer with dashboard lamps
Couldn't hurt trying.

Good hunting

Neutron,
ive seen that site, I would like to keep it original and not hard wire stuff so still prefer to find the wheat lamps.

Xeaglekeeper,
I looked at that site, but they dont have bare wire leads, so wont fit in the holders.

ess44,

took your advice and rang around, but none to be found.


I cant believe I cant get in touch with any one from Denon regarding parts for this and a service manual, its insane. the NZ agents listed on the website has a disconnected phone line, no email. Very unprofessional of Denon. I cant contact anyone from Denon International cos they dont have email, also Denon UK ignored my mail. I dont think I will buy this brand again.
