hello friends,

I havy buyed a Philips PT1310 Kurzzeitmesser (short time counter)"Elektro Spezial",
this oldie use a set of 6 modules with each one E1T dekatron buizen

[image]

it would be very helpful in restoration to have the manual from that,
so I am asking if I can find it anywhere.

thank you much for help.

Elektro Spezial was a german company located in Hamburg, they was buyed to be a part of Philips. So this old instrument is a made in germany by Elektro Spezial, but a true Philips :-)

"PT".

PM is a Philips testequipment.
PT is (not shure..) a Philips Timer, a clock or what? It is build like a test equipment.

greetings
Martin

Very interesting! Never seen that one before.
I would love to see some inside pictures :-D :OK:

Regards, Roland

hello Roland,

I will post a complete restoration report including a video from the working apparatus :-)
This is a fun project. The instrument will be used later to count the time you need to drink empty a glass of beer, on meetings of old radio collectors (I go some of them yearly) :-D

The german jogis roehrenbude have a report, also from this modules.
They seems to be finish to buy from Philips bec. when you look in the datasheet from E1T the voltage window from this tubes is so very small that they have to use 1% resistors. This accuracy was higher then the of the most used test equipment in that time.

a friend have read that I will restore this and have sent me a mail, I will get also a Rohde+Schwarz FER in the comming week.

see http://www.radiomuseum.org/r/rohde_elektronischer_zaehler_fe.html

This is a counter test equipment, also using 3 pcs. of E1T (without Philips modules), and for the higher ranges a elektromechanical counter. From that apparatus I can also post the restoration report + video when it`s done.

My hobby is the care and collecting of vintage test equipment (mostly Tek) :-)

Hello Martin,

I'm not sure what the T stands for, but I know that Philips Industrial introduced a new type number system with a P and a second letter indicating the category at some point in time. Most likely this new system was introduced between 1963 and 1967 at the same time the 12NC coding system was introduced for the industrial equipment production (when you take pictures, could you make sure to include any type/serial/code numbers and date codes? This will help my data collection greatly so I can better determine such details).

PE = power supplies
PM = testing and measuring equipment (meters, signal generators, frequency counters)
PP = ? (slotted silver line meter, bought in from Marconi?)
PR = lab equipment? (stroboscopes, conductivity meters, strain gauges and load cells - which was also a Hamburg Lockstedt specialism)
PT = ? (this timer)
PW = lab equipment? (radiation meters, pH meters, conductivity meters)

hello Maarten,

you will get all information I can find. :-)

The time focus of this E1T machines is around 1960.

Actually "PT" is a philishave :-D

so the restoration of that Philips Oldie can begin.
It is larger then i thought, a hughe instrument !

it works :-)

the count is 99,9999 seconds.
the >,< is a little bulb behind the second tube.

Martin,
Great!
Quality stuff :-D :OK:

Let it count a bit slower then at the lowest tubes we can see the count better.

Think you can trigger the counting?
Then it should be possable to count a sinus wave form perhaps.

Look at newer manuals of counters to see what and how to count
signals.
Should be not that different.

that oldie use a crystal of 10kHz.

I thought at first this is a neon lamp. but it have 4 wires.

seems to be a little warm diode, EA76 or like that :-)

Or perhaps a trigger tube?

it is a little Diode.

Very closed to a half of the E91AA

Actually I am working in the PSU.
There is a counting problem, "9" jumps directly to zero.
The tube datasheet from E1T tell us from 156V +- 1,5% and 11,9V +-150mV what is required. I found Overvoltage, +165 and +14,5V. This will be repaired to provide the required voltages.

Then I have to check the counting again.

At last the oscillator module must be RE to get a application from it, so I get to know how the input lines work.

greetings
Martin

I have repaired something in Voltage from the PSU:

required // true

+300 +313 (no change)
+156 +157 (there was +165V but the data sheet E1T needs 156V +-1,5%)
+11,9 +11,95 (there was +14,5V but the data sheet E1T needs 11,9V +-150mV)

now it counts the 8-9-0 exactly :-)
