This is part of a video series about the Wollensak 1288 Stereo Tape Recorder Restoration done by ClydeSight Productions - www.clydesight.com - in early 2012. This video discusses the problems ClydeSight encountered with the tape recorders amplifier. Fans of Wollensak machines, especially the T-1500 and T1400 series of tape recorders will recognize the similarity of the components among these reel to reel tape recorders, but may find some interesting revelations in how Wollensak engineered a stereo amplifier with discrete channels based on their successful monophonic designs. The video also reveals how what seemed like a simple and solid soldering system and circuit board design could go horribly wrong and create arcing and actual destruction of the circuit board itself. In fact, if ClydeSight had not gotten the tape recorder, it is possible that it could have started an electrical fire for another owner who did not know much about these machines and what to do when they start to smell bad and smoke. Among the failures in the amplifier of this vintage tape recorder were two "dual can" electrolytic capacitors. They are no longer made, but ClydeSight came up with an ingenious replacement solution that viewers may find insightful and fascinating. The Wollensak 1288 stereo tape recorder was issued in 1965, based on the well known and extremely stable transport used in the Wollensak T1500 and 1400 series of mono tape recorders. With the 1288, Wollensak introduced a fine quality ...
