This is not a simple tape delay unit - there are two independent sections with separate input/output with more additional analog effects.

serial #0285004

4 delay times is fixed with buttons - You can use for any from 4 delay times simultaneous.

On the right side of unit is two line inputs: MICROPHONE 1 and 2 and one Mono output - For this section You can use tape delay only.

On the left side is two other inputs: GUITAR Input - for this input You can apply tape delay, fuzz (additional SHIMITTER FX for fuzz - more harmonics and O. - octave down), tremolo and filter, controlled with external pedal. External pedal is not included.

For ORGAN input - You can use tape delay and shmitter.

Right section - mic-in 1-2 levels, reverb level, echo level, power on

Left section - guitar-in level, organ-in level, pedal on/off, reverb level, echo level

Middle section - vibrato depth, vibrato freq, fuzz on, shmitter, octaver, vibrato on, 4 variations knobs (filter).

Reverberator uses the circular tape. You can switch the motor on/off, so the tape is preserved. Power supply 220V/240V.

Jolana KolorBas 4-string bass guitar, 1972, made in Сzechoslovakia

Link: cheesyguitars

By the end of 1972 Jolana plants in Hradec Kralove and Horovice started production of two new models, which were Rubin and Kolor guitars ans basses. They used exactly the same semihollow bodies on guitar and bass, only the neck and the hardware were different to accomodate diffetent scales and other details. The bridge was a new simplified design, with independent saddles for each string. The only difference between Kolor and Rubin models seem to be the headstock - while Kolor had all tuners on a side, Rubin had a symmetrical 3+3 (guitar) or 2+2 (bass) arrangement.

The name suggests some colours, and here it is - a shocking blue finish. Kolor basses were finished in different colors of the rainbow, with painted headstocks, necks and virtually everything. No sunbursts.

Dynaco A-25, 1971, made in Denmark

Link: hifiengine | dynacotubeaudio |t-linespeakers | vintage-speaker-review

The classic A25 used a SEAS 10" alnico midbass & a SEAS 1 1/2" alnico treated textile dome tweeter with a 1kHz XO. The later A25XL gained 3 dB of efficiency by utilizing a ceramic SEAS 10" and 1" tweeter


The Dynaco A-25 aperiodic loudspeaker is a compact, high performance two way speaker system.

A 10 inch extended excursion woofer is matched to a specially designed soft dome tweeter with a dual section high pass filter at 1500Hz, in a cabinet design which achieves a uniquely non-resonant bass response.

The aperiodic, or non-resonant characteristic of the A-25 provides an unusally uniform impedance characteristic throughtout the bass range of less than 2 in 1.

This design utilises an acoustic impedance system which provides variable volume action rather than the totally enclosed cabinet of the acoustic suspension principle or the tuned port of the bass reflex.

Type: 2 way, 2 driver loudspeaker system
Frequency Response: 30Hz to 15kHz
Power Handling: 35W
Recommended Amplifier: 60W (maximum)
Crossover Frequency: 1500Hz
Impedance: 8Ω
Bass: 1 x 10" extended excursion
Tweeter: 1 x soft dome
Finish: oiled walnut, rosewood, teak

Tube Stereo Amplifier

Усилитель ламповый двухтактный. Реализована схема с трансформаторной связью между каскадами, драйверная лампа 6с45п, лампы оконечного каскада г-807 (включение триодное), режимы ламп соответствуют рекомендуемым, выходная мощность 6Вт.

Усилитель состоит из 2-х блоков:

1-ый блок: Блока питания в основе которого лежит плата БП от Lynx (обеспечивается плавный пуск), силовой анодный трансформатор на железе R-core с двумя вторичными обмотками для раздельного питания драйверного и оконечного каскада, накальный трансформатор Edcor и отдельный трансформатор Fisher для питания логики и реле платы плавного пуска. Конденсаторы Epcos и Nichicon, быстрые диоды. Линии питания от БП к блоку усилителя защищены плавкими предохранителями. Материал корпуса нержавеющая сталь, передняя панель- алюминий.

2-ой блок: Блока усилителя. Корпус целиком из нержавеющей стали, нижняя пластина и пластина на которую установлены выходные и межкаскадные трансформаторы толщиной 4мм. Выходные трансформаторы Hammond 1615, межкаскадыные (в кожухах) Lundahl 1692a (Alt V SE to PP). Резисторы Dale.

Усилитель является по сути качественной реализацией схемотехники 30-х годов прошлого столетия. На пути сигнала отсутствуют разделительные конденсаторы, да и всего на пути сигнала 5 деталей (6с45п - Lundahl LL1692a - Резистор (Dale) - Г-807 - Hammond 1615). ООС отсутствует. Отдельный БП позволяет максимально развязаться от сетевого фона и вибрации.

В комплекте пассивный предусилитель (на фото справа) на базе Alps.
