Yamaha MC2404 mkii [Restoration & Repair], 1983, made in Japan

Используемые в работе гаджеты:

- флюс mob39 (France) в паре с Hakko wick (Japan)

- Весь демонтаж производился в обнимку с Metcal MX-5200

- Вся пайка производилась на оригинальной станции JBC с жалами этого же бренда, припой только Loctite

- Чистка смазка Kontakt PR / 60 / 61

- Дополнительные смазывающие Forch 439, Molykote

ну вообщем получилось так что расходники стоят дороже чем устройство, но есть такое понятие как Любовь к винтажу, этакие эмоции...

Klemt Echolette Solid State Panorama Mixer with Spring Reverb [Restoration & Repair], 1971, made in Germany

Link: cliff-shadowsmeeting

The Panorama-Mixer is an upscale pre-amp mixer from KLEMT's new series of devices. It has five identical mono jack inputs for the unbalanced connection of microphones or electronic instruments. With a level controller and a negative feedback circuit, the gain of the input amplifier can be optimally adjusted to the level of the input signal. Each input channel has a panorama control with which the input signal can be continuously mixed into the two output channels. Each channel has a three-band tone control that allows you to adjust and change the sound as desired. As a special model, the Panorama-Mixer was also manufactured with an integrated Hammond spring reverberation system. To build a powerful vocal system, two 160 watt STENTOR power amplifiers can be combined with the Panorama-Mixer.
