This Webcor 2110, ca. 1952, found its way into my collection of anachronistic, incredibly useful toys.
Oh Joy!
Moving parts are always more amusing for sound playback toys
This deck records and plays a monophonic signal in both directions - when the tape is near the end of the reel, you turn a knob to reverse the direction of the tape "...without bothersome reel turnover." 😃
There are two tape speeds - 3 1/4 and 7 1/2 inches per second. On a 7 inch reel, you can get a delightful 2 hour recording 😅 with an astonishing frequency response up to 10khz, with less than .5% wow and flutter. Original price, in 1952, was $207.50.
Detail of the high-tech tape time counter
Beautiful mic - still works
These images are from an initial evaluation. It has all of the tubes, and is mechanically complete. Subsequent posts will go into more detail about the mechanical restoration for each section, followed by the electrical work.
First look under the cover...
Closeup, along the tape path by the heads. One head is in contact with the tape, and they alternate with tape direction. Eventually, I'll post little videos about the very unique mechanisms.
Head wear and oxide buildup. Always have dice on hand as little repair positioning aids 😄
Inside the head case (so to speak)
Missing some of the felt pressure pads. These gently press against the tape for good tape-to-head contact.
Schematic
The tubes are common if they are needed. The tricky part is whether the worn heads still work - aside from wear, sometimes a fine wire inside the head assembly will break. Heads are very rare. If they are shot, this still makes a great little guitar amp, for that sweet tube sound.
