#1 Mazda pp3/250

Post by Stuart Dean »

Just returned from a car boot sale with a pair of Mazda PP3/250.
The seller wanted £1 for the two.
He didn't have change for a tenner and all I could raise in loose change was 85p.
So he gave me a discount.
I did return later and made up the asking price. This was the least I could do but really I had no idea just what the PP3s were but looked most certainly like triodes.
Apparently the were the Mazda equivalent of the PX4
Not able to test British 4 pins with my B and K but the filaments are OK.
Just checked on a couple of last years ebay sales.
Mmmmm.

Yes Stuart, what he said, you lucky bugger :)
They are probably shot so you can send them to me straight away for safe disposal. :wink:

Yep, according to National Valve Museum

Yep they are exactly same as the one illustrated on National Valve Museum page.
Apparently they are the early version which first appeared in 1932.
Just a few years older than me then!
A few years ago I was finding valves at boot sales nearly every week.
Last year I found 3 and until today nothing this year.

That was a great find.

Not seen anything decent at the big boot fairs around here (near Tunbridge Wells in Kent)... No valves at all recently (last few years).

Can't complain - did get the Quad 405-2/34/FM4 (pristine) for 10 quid the lot last year, but I don't ever expect to find anything like that again...

There's an old boy who turns up from time to time with a box van full of weird stuff - he clears old labs & store rooms for a couple of the London University colleges. Occasionally has Tek scopes and bizarre stuff like peristaltic blood pumps and bits of kidney machines... not usual boot fair bits...

Has the audio world gone completely crazy!!!
At the start of this post I related how I had aquired a pair of Mazda PP3/250s.
At the time I had absolutely no idea of what they were except they looked like triodes.
When I bought them I was looking through a box of old photographic junk searching for vintage lenses.
I ask the seller if he had anything else and he produced a half full black dustbin bag and tipped the contents from the hight of around 60cm into the box which was on the ground.
First one and then the other PP3 appeared and survived the ordeal
On returning home I did the search to establish exactly what I had bought which was quite a pleasant suprise.
Then did another quick search to found a pair had sold on ebay for £230 another pair went for £560 and finally two went to Korea for £720.
At a bit of a loose end this morning I did an ebay search to see what the present situation was.
One single PP3/250 offered with 10 bids at the moment at £238 and a pair of N.I.B ones in Hong Kong offered with a Buy it Now price of around £2800 (He did offer free shipping!)
I would really like to pass my pair on to a AT member to play with but in view of their potential value and that I have to live in the real world I don't think I have any alternative but to either hold on to them as it's unlikely that they will decrease in value or to sell via ebay.
I would need to contact a friend with an AVO CT160 to get them tested because they my be completely knackered.
Also I would hate to ship these anywhere as the extremely long filiaments must be very fragile.
What a dilema.

Get them tested, and if OK put on e-bay.

Just realised the H.K pair are not Buy it Now but the £2800 is a starting price.

If rare and desirable will cost lots. :lol:

I agree only if they work well. If not, they're junk

Or you could build an amp with 'em.

If they work....
