Any ideas on where to find a replacement valve.3663

1265850 2012-03-19 08:05:00 Maybe contact the NZ Vintage Radio Society, I think they have garage sales, (www.google.co.uk) but probably need to be a member. kahawai chaser (3545)

:) Further to Trev's post, it is most important to know what the valve type was, but since the glass is broken reading it is not an option unless there are some very big pieces still available so look and see.

Next best is to see if there is a valve location and type diagram on the back or pasted inside the cabinet. If so, you are home and hosed.

If not, and there is a model number on the back, that may be of use if you contact the local branch of the NZVRS, but if that option also fails, write down the type numbers of the remaining valves (if it has a magic eye don't bother with that one, just mention it has one) and from that line up it should be possible for most enthusiasts to deduce the right type number. Be careful removing the existing valves as you can easily wipe off the numbers with your fingers, try to wriggle them out by holding the bakelite base.

You won't find valves of that age for sale anywhere but on TM or in the hands of vintage radio restorers (I have about 800!) however there are a couple of companies run by enthusiasts that do sell old valves so there is every reason to expect that you will be able to get the valve you need, and at a moderate cost.

If Trev can't help you, PM me if you need further assistance, I am a member of both the NZ & Oz VR societies and can buy just about any common valve from the Oz valve Bank at a very reasonable price.

1265853 2012-03-19 08:38:00 Is that faint writing on the base of the valve or just scratches ?

1265854 2012-03-19 09:34:00 Yes I noticed the scratches in the photo. The writing is very worn out but could be SY WANIA and below is Made in USA. Bobh (5192)
1265855 2012-03-19 17:02:00 You actually need a number. I will try asking around with that photo for you.

1265856 2012-03-19 20:41:00 Bob, I used to have hundreds of them but I gave them to a Mate who was a real enthusiast. Unfortunately he died and I fear his Widow may have dumped them.

However, I still have some so can you give us a photo of the base of the valve so we can see the number of pins, and it looks like it had an Anode connection on the top? Can you confirm that?

Also, a photo of the Chassis would be helpful so we can see where it sits and also the numbers on the other Valves. These are all clues which will help with an educated guess. Valves that sit between coils and those by the power pack are a clue as to type and some were often used in conjunction with others which is why I ask.

However, be careful when inspecting the others not to put your fingers on the glass of the Valve or you may loose the numbers off them as well. If you think you can see a number or letter on a Valve try breathing on it. Sometimes that helps show the critical bits.

Good luck.

I have to get back to work but I will post the photograph of the base as soon as I can. Thanks for your help one and all.
