Produktbild Flash news from the Scopeclockland:
First time ever since we started dealing with tubes we are able to offer orange phosphor scope tubes.
Those run excellently with our scopeclock-kit.
All information on our scopeclockpage.
Produktbild Flash news from the Scopeclockland:
PID-Module as add-on to our scopeclock kit: This switches the tube dark whenever there is nobody close enough to look at her.

This simple measure prolonges tube life enormously.
Those run excellently with our scopeclock-kit.

Stock clearance
We do still have a huge stash of 1950-60s tube radio chassis, mainly of german make.
To throw those away would hurt us so we sell them for parts.
Each of those will contain at least
- The power transformer, mostly multi-primary.
- The chassis with tube sockets, small parts, push buttons, IF-Filters, binding posts etc.
- The variable capacitor, usually air tuned, 2-4 sections
This is an excellent point to start if you want to tinker with tubes, no need for
sheet metal work and chassis bending.
The photo shown here shows examples, sorry, we can not pick specific chassis for you.
Price per chassis: EUR 5 / 5,95 ( net / incl. VAT)
Order code: Chassis-1

New item:
Same as above, includes also the output transformer.
Easisest start for a small tube amplifier project.
Price per chassis: EUR 10,- / EUR 11,90 ( net/ incl VAT)
Order code: Chassis-2

PLEASE CONTACT US for shipping cost, those are fairly heavy but we will work out the best
possible shipping rates for you.

LM317 regulators. This is a very nice project to show kids and teenagers electronics
The board is really generous in size, easy to solder.
Kit contains of the circuit board and the parts to populate it.
Additionally you will need a suitable transformer, a cable power supply ( like those used for laptop computers
or a suitable wall wart.
This is not a toy, experts must be present when this kit is being assembled.
Take note: all documentation is in German language - though the circuit diagram is quite self explaining.

Long time expected: a small SE OPT with about 1W power rating to be used with
- Battery tubes: replaces the OPT in almost any battery powered radio (with SE amp)
- Small power applications, if you use high efficiency speakers and like low power amps
- Headphone amps
- or as step.up interstage, ratio 30-50
Primary 8 and 10 kOhms, 15mA max, sec. 4 and 8 ohms.
German made quality.
For details and prices see our OPT page
Produktbild Microwave feedhorn sets
For licensed amateurs who follow all rules and regulations:
Set of two feedhorns with surrounding electronics, we have absolutely no data and
information about those so this is a totally experimental project. Also nice for
teachers to show students the basics of microwave radio. Order code: AF9784, Photo similar, actual products may vary very slightly.

Cloth is difficult enough as collections are subject to fashion..
We found a few very nice cloths, see our
sparepartpage for details.
High power Doorknobs rated 1,7nF to 3nF (1700pF to 3000pF) at 40kV and 50kV (!!)
Those are excellent caps for Teslacoils, marxgenerators, high current applications etc.
One customer built a teslacoil and allowed us to publish a video of his tesla coil operating. Here it is !
Those are used, tested caps from disassembled industrial applications. They are oil-resistant so no problem to use them immersed in oil.

Detaileds datasheet: If you want one, mail us and we will gladly send you one.
New arrival: 6B4G Sylvania Power triode, NOS, former mil. stock.
Now you can build real triode amps with real western NOS tubes at a very attractive price.
Ex mil stock, individually boxed, early 1950s production

completely parallel plates.
Tubes are being supplied with curvetraces and detailed testsheet, also paired and as quads if wanted.
New horse in the stable: The "Roetest" from Mr.Weigl.
This is a computerised precision tube analyser and measuring system allowing many different tests, curve tracing and much more.
even THD can be calculated.
We offer this as additional service at a fixed price per tube.
New High Grade film caps in the range between 1 and 10 uF. Fine selection of ratings to cover this range.
Now all ratings between 47pF and 100uF are being covered. Those are excellent caps for crossovers, PSU, bypassing, coupling etc.
