Guest book 2002-10 (under construction)
I am well behind with this page and have loads of useful emails to put on - bare with me, my new resolution is to sort this out!
One nice thing about running a web site is the numerous emails you get from people interested in the same things as you. Aside from the "how much is it worth" requests I get some very useful information and some lovely stories that add depth to the dry images and descriptions of Vintage Technology. Please be aware that your email to me could end up in this page without your specific request not to (please request removal if offended, or just want your name removed). Comments in  are edited out by me as some items are too sensitive to put on the web.

manufacturer, this means plainly: Deutsches Reich Patent.
The manufacturer of this instrument is Neuberger, well known for Valve Testers.

|Subject:||BEAUTIFUL SITE !!! (Brimarize)|
|Msg:||Hello Emil, I'm a
guy from Malta who came across your site while doing a search on Brimar.
Very WELLL DONE!!! Beautifully laid out your site is indeed a pleasure to
I would like to ask you a question about the "Brimarize Sheet No." mentioned in the Substitution List of the Brimar Manual - mine is No.6. Apparently Brimar published a series of Sheets which however do not feature in the Manual.
I made a search on 'Brimarize' and got only one link to the diyaudio.com forum (which I visit often, as I'm interested in audio.) Then I tried just 'Brimar' and voila' got to your site.
Thanks a lot for your help.
Thanks for your email and kind words.
I do not have any Brimarize sheets - sounds like a "how to convert the valve to a Brimar one that isn't an exact plug-in" instruction. I do recall having heard it before, however. What sort of date were these about? That would help me try and look it up.
Yes, it seems that is what "Brimarizing" basically means. As to their date, the manual I have (No. 6) has no print date. However, the price list at the end of the book says it is effective as from July 1956. Interestingly, there is a 3-page section on Transistors featuring types TJ1, TJ2, TJ3; and TP1, TP2, all referred to as "Germanium Crystal Triodes" !!
Hope this helps. Thanks and best regards,
|Subject:||Date codes on GDR chips|
I just found your page about calculators.
For the GDR model MR 201 you obviously guess only about date codes.
Ok, here some little help with this.
The first letter is the year, the second is the month. See also this page http://www.elektron-bbs.de/elektronik/tabellen/datum.htm It is in German, but the names of months aren't that different ;-)
|Reply:||Thanks for that - really useful - I will correct the entry and put a link to this page.|
David, thank for your email and memories.
