Czechoslovakian measure equipment collection

[Bored@Work]

I was told that every czechoslovakian test instrument was a clone of some western with 10 year delay. Could you please someone write here WHICH is M1T330 clone of ?

From the outside it looks a bit like the crossbreeding of a Solartron 7045 with a Solartron 7150. Or it could be something completely different. Not that there are many design variations if you want to build an ergonomic bench multimeter. Display on top, switches below, sockets left, right or below the display

I'm surprised T4P hasn't chirped in with his opinion...

Anyway. Thanks for sharing these photos of your test gear. I really love analog circuit boards, they have a charm and personal touch that modern PCBs don't.

Cheers

Very nice pics and instrument, I cannot figure out the isolated interface,
do you have some closer pic of toroids?
Do the white wires go on the bottom of pcb and then come back on top
on the other side?

Thanks, Fabio.

The transformers and some of the transistor bodies and trimmer bodies  in these devices lead me to believe they are clones or partnerships with Philips instruments...

If the M1T 330 was 'state of the art' in 1984 then it was 10 to 15 years out-of-date compared to western machines.
Even old Keithley machines like the 187 were much more integrated than this ...

chips like the ICL7106 and ICL7109 have been around since the mid 70's ....

Hello Metracollector, as a big fanatic of eastern electronics (I have a huuuuge collection of soviet electronics) I must thank you for these photos, and hope you will post more. Let me share here a wonderfull link from a russian forum, were lots of instruments are taken appart: http://offtop.ru/dustyattic/v1_700390_1.php . For whoever is interested in easten devices, this link is somewhat awesome. I have a big soviet C1-99 o'scope in the attic, I may post a teardown here sometime soon, together with other ones.

Awesome link- I think I recognize some of the units I used to own, but was not allowed to take apart!

It does look very "Philipsy",but that is not uncommon among European equipment,even from "the West".
Overall,all of the Eastern Bloc stuff I've seen on the 'Net has a lot in common with West European ways of doing things,with a lot of it looking very like either,Philips, Rohde & Schwarz,Wandell und Goltermann,or Siemens,& distinctly different from stuff from the USA,UK,Japan,or Australia.

Thanks for all the nice photos of the interesting test equipment. My father, who passed away a few years ago at age 89 was born in the Czech republic. I went there on summer vacation when I was a kid with my parents in th 1970's. My father moved back to the Czech republic in 2006 after my mother passed away, and was stayng with a relative, me and my two older brothers went to visit him in '06 & '08. He was living nearby a small town called Bruntal (he was born in Ostrava).  I enjoyed my visits there, it was also nice to sightsee in Prague, beautiful city.

Greetings to you from New York,

Fred

Hi MetraCollector & M1T 330,

I am a radio amateur and own an old/vintage magnetic field meter. However, the probe is open or possibly broken.

Do you know where I can get a probe like this?
Is it possible to fix it myself? For that I need to know how it is assembled.

I have attached pictures to this email.
I hope you can help me reuse this precious old instrument for my measurements. Thank you

Sincerely,
Tzvetomir
