Tascam CD-GT1 Portable CD Guitar Trainer, made in Japan


Link: tascam [Manual, PDF]

The TASCAM CD-GT1mkII Portable CD Guitar Trainer is the ultimate training and jamming tool for guitarists, vocalists, and other musicians. Take any favorite CD, plug your guitar directly into the CD-GT1's 1/4" input, put on some headphones, set the volume, and start rocking! Vocalists can do the same with a mic.

The Slow Speed Audition feature lets you learn licks note-for-note by slowing down the CD up to 50% without changing the pitch. You can also increase the tempo in steps until you match the original performance. Added features include a guitar-cancelling function, built-in metronome, and oscillators for tuning, and split monitoring.

Advanced players can use the CD-GT1's pitch and speed controls to audition various keys and tempi for CDs they've burned of their own music.

The CD-GT1 has 57 great-sounding, customizable effects including distortion, delay, chorus, and more. There's also a nice selection of vocal reverbs and processed sounds so you can sing along with rockers, hip-hoppers, divas, and everything in-between!

You can set seamless in-out loop points with the CD-GT1 so that it plays the same passage over and over again so you can nail phrases. Use the footswitch input to start playing the CD from any designated point or to scroll through effects.

You can listen on headphones, or use its line output to plug in speakers. The CD-GT1 even provides a chromatic tuner and operates on batteries to take your show on the road. Optional AC power supply. (See accessory box on this page.)

Saba Permadyn Greencone 19-200 1670 DU 15 5Ohm Tweeter - Open Baffle, 1962, made in Germany


These tweeters are some strange creatures having the dust cap fixed to pole piece by a brass screw, thus a rugged mechanical high-pass filter. The impact on frequency response from this is a broad peak centered around 12-14 kHz, 15 dB above basic level - and some 10 dB above the average response from the 8" driver. Those who choose to run their tweeter from a single cap alone, usually 2.2 uF, certainly get some upper treble level!

Особенности:

  • оконечный усилитель собран на: 2 x Ates AL113 & 2 x Ates BD163 
  • конденсаторы есть только на входе - два зеленых и два серебристых по 2200 mkf на выходе 
  • В цепи сигнала больше конденсаторов нет. 
  • темброблок реализован в цепи обратной связи - поэтому обошлись без конденсаторов. 
  • схемотехника - оч близок к схеме класса А
  • исполнение - аналогичен Perpetuum-Ebner PE HSV 22 (понятно что транзистора не 2 а 4, BC слабее и т. д)
Звук благороден. Нч плотный и низкий, собран. Сч чистые на супер.вч и рупоре.

Менялись транзисторы BC на са968 что лучше и надежнее, в обвес поставлены большие радиаторы. Все остальное не тронуто.

Что дала замена на са968:

  • в открытом состоянии сопротивление коллектор-эмиттер меньше ⇒ меньше греются и стабильнее работа 
  • граничная частота в 2.5 раза выше 
  • коэффициент усиления больше

Is a wonderful performance that can be played from 2kHz or less to 20kHz. The output of the voice coil error or 304 is about 2 dB lower, but it is an error that cannot be detected when listening with the ear.
