Donor: Tibor Schroder.
Videoton's second generation (RT-402) high-fidelity Hi-Fi tower amplifier. Additional features of the tower include Videoton RT 6303 S tuner, Akai AP-Q310 / C turntable, Akai CS-F210 tape recorder, VT DC 2550 speaker and SA7 stand.
Its predecessor is the VT EA 6380 S, which has changed a lot. Interestingly, when you touch the buttons, the electronics mute the amplifier so there is no noise or bump on the loudspeakers when switching on. Its amplifier includes BD809-BD810 high-purity transistors, but the same can be said of the other semiconductors used in the final phase. Despite its active use, the last bolt is in its original, flawless and scratch-free state, making this amplifier even more special.

The PowerBook G4/1.25 15" (FW800) features a 1.25 GHz PowerPC 7447 (G4) processor with the AltiVec "Velocity Engine" vector processing unit and 512k on chip level 2 cache, 512 MB of PC2700 DDR SDRAM, an 80 GB Ultra ATA/100 hard drive (4200 RPM), a slot-loading 2X DVD-R/CD-RW "SuperDrive", a Firewire "400" and "800" port, built-in Bluetooth 1.1 and AirPort Extreme (802.11g), and ATI Mobility Radeon 9600 (4X AGP) graphics with 64 MB of DDR SDRAM in an attractive aluminum alloy case with a 15" widescreen TFT display (1280x854 native resolution). Custom configurations also were available.

The PowerBook G4 "Firewire 800" series adds AirPort Extreme (802.11g), Bluetooth 1.1, USB 2.0, and Firewire "800", as well as a faster logicboard and memory, to the 15" models.

Please note that unlike the otherwise similar PowerBook G4/1.0 15" (FW800), the PowerBook G4/1.25 15" (FW800) has the fiber optic based "ambient light sensor" that automatically "measures ambient light and works with integrated software to adjust keyboard illumination and screen brightness based on user preferences". The PowerBook G4/1.25 15" also has a faster processor, twice the default RAM, a larger hard drive, a more capable optical drive, and pre-installed AirPort Extreme (802.11g).

Electronica Venta-Flanger PE-11 [Электроника Venta-Flanger ПЭ-11], 1991, made in USSR

Link: cheesyguitars | effectsdatabase | reverb | upgrade: in/out power supply

A Russian flanger PE-11. We suggest this one was produced after 1990 since the labeling is in English. The units seems to be a successor of Elektronika FL-01 flanger made by the same factory in the early 80's.
One may wonder what "manual" control does. As far as we know, it brings a little LCD screen with instructions how to use the pedal and when you turn the knob, it scrolls the text. The absence of the footswitch is another trick - there's a little voice sensor you can see on the upper left part of the pedal, and when you scream "Flanger!!!" it turns the effect on and off. Unfortunately, the "manual" and voice control options were broken on this particular pedal, so we had to take our best guess.

Педаль среднего перегруза. Включается, и выключается как и все Рижские педали нажатием педали до упора, что не удобно т.к. можно нечайно выключить в самый непододящий момент. Так же это еще и самая маленькая педаль Рижской фабрики, остальные заметно больше в длину.

Фузз на двух кремниевых транзисторах. Регулируется уровень громкости и тембр (по современному гейн) сигнала. Платформа нажимает только на кнопку байпаса.
