Here are pictures of tubes and tube devices.




Philetta 12RB273
Radio

The first two are of my Philips Philetta from year 1967.


TK-23L
These three are from my tape recorder, also 1967.


Magnetophon 76


Sichtgerät C72145-A20-A2



A CRT monitor built in 1966. When I managed the unit with about 25 kg after home, the mandatory cleaning. Then carefully first plugged into an outlet that ran something like wax from a suppression capacitor. Was so designed only for 220V (we have 230V now) and I do not know how long it was no longer in operation. After replacing them with 250 V voltage rating, it looks even better for the boob tube.:)


Pictures from different devices


C-1405 G




ICF-SW1E


Almost 20 years ago this world receiver one of my most expensive purchase with about 470 DM was It is the version with full 150-29995 kHz (LW, MW, SW) and 76-108 MHz (VHF extended). Some time ago, I need to change a few dried out capacitors.

Here pictures are devices built of.


smartkit 1045

My first ones is the SmartKit Electronics 1045. A Soundgenerator.


Stereo-Soundsampler

A Sound-Sampler for AMIGA.


UCR-80 Centronics-Relaisinterface

8-channel-relaisinterface for parallelport.


UKW-TX 5 W

Mono FM tranceiver 80 - 108 MHz with 5 W output.


VLF - FAX - RX

This is a VLF-Fax-receiver for the very long wave band of 75 - 150 kHz.


FSK - RTTY - Decoder

FSK-/RTTY-decoder for a serielle computerport.


VCR-TV-Tuner

A VHF-/UHF-Tuner with Nf-amplifier and tone change over switch. It has antennas -, headphones- and AV- connection. The power pack is a ringcoretransformer with 14 volt.


Monitor Amplifier

12 volt stereoamplifier.


Tischgerät Tuner + Cassette + Amp

From a friend I got this old desktop device of Schneider (record player was defective) and built it into a plexiglass casing with bulbs and IR switches.


Konzertmeister 2000 Tubeamplifier (DIY)

In an old housing of a cassette deck I built a tube preamplifier. The used tubes are two ECC 83 and two EL 84. I took over the switches, buttons and controlling announcement (fluorescent meter) from the cassette deck.
In the meantime I converted the tube preamplifier to a full amplifier. For the connection to two 4 or 8 ohm loudspeakers I inserted two new transducers, as well as a new supplytransformer with more power. Instead of recording level indicator now a "magic band" (type PM 84) is in it. Here it gives my connection diagram of the tube amplifier: Konzertmeister 2000.FH8 or PDF



Musimoog Tubesynthesizer (DIY)

A Tubesynthesizer with soundgenerators, bassbooster und vibrator. Sheets from my "Musimoog":
Synthesizer.FH8 or PDF
Soundsampel:
Sounds of Musimoog.mp3

WIP: Built the synthesizer in a 19"-Case with more tubes.


Powersupplies

Different supplies .


LED - Linelight (DIY)


Low Power "lightart" with 18 Low-Current-LED´s on a solarpanel with 12 VDC.


AnalogSynth Formant Synthesizer (DIY)




In a 19"-case I have a analogsynthesizer built in. There´s in now from left to right: Supply +- 5 / +- 15 volt, VCO (sawtooth right up), LFO (tri- , rectangel right middle), white-/ pink-noise, PWM with NE 556 and sequencer with CMOS.

The sheets here:
Analogsynth

After I still another a ring modulator and filter had inserted, the front plate became quite full.
In the photo left down one sees the synthesizer between the tubesynthesizer and a function table with rectangle/sine signal. Right down individually.


RGB-FBAS testpic
rgb - testb

Platinenpuzzleanhänger

In May 2012, I got two puzzle pieces made ​​of platinum residues given. On one I could build a small turn signals.


Oszilloskopuhr (Fertigbausatz)

Also on analog oscilloscopes can display a clock. :) Creates she is from an AVR Clock V2.7 of Dutchtronix. At the resolution you would still screw something, but is only a gimmick.


Modellhäuschen mit RGB-Lampe
Hausbau
Häuschen 1 Häuschen 2

Selfmade cottage with a purchased RGB LED lamp and IR remote control. To this end, I would just need a guard dog. :)


Mashinelights



An ATMEGA48 control FETs BUZ90. On the slopes, the 5 24-volt lamps of the traffic lights. The lighting effects should be selectable by pressing a key.
