Here you can see the replacement capacitors and the recommended upgrade replacing the driver transistor resistors with 100R 1W Flameproof ones. Read this PDF (coming soon).įirst you MUST replace all the Electrolytic Capacitors found in the amplifier - the ones on the circuit boards and the ones on the underside of the amplifier chassis. This amplifier needs a couple of modifications done to ensure it will stay reliable, and - if a problem occurs - is less likely to have major transistor failures. The two pictures show the arm that must move freely when the tower is out of the machine, and the clip to remove to start the disassembly. If your Seeburg is repeating same selection without advancing to the next record, skipping past selections or reacting too slowly to go into play then chances are your pivot in the clutch tower has seized up and needs to be taken apart.

KD 200 - lift lid, lift keyboard forward, lift keyboard again to get past stop so it lays down completely forward, then lift one of the three wires the same as for the 201 above (no plastic tubing on these wires): How to remove the red 'tailight' dome lens covers from models KD200 & 201 to replace the light bulb (#55 or a #455 for flashing):Ģ01 - lift lid, then lift the wire (covered in black plastic) enough that the dome will turn about 1/8 rotation counterclockwise.

Typical lubrication points (PDF) for the Seeburg mechanism. Also, add a short jumper wire between the speed control CASE, to the common grounds on the relay contacts (black wires) as there are schematics that show this ground on the wiper side -wrong- that would short out the control! Ron Rich says (edited by JR):To update either a 45 TASU-1, or -2 AUTO-SPEED to a code C unit add, if not there, a 1.0 x 200V mylar capacitor to each of the two transistors between Collector & Base terminals. I (John) use one of the two lead neon bulb test lamps you can still buy at hardware stores.they work pretty well for doing the Seeburg tests. Ron Rich says: 'The 'test lamp' consisted of a NE 51H, lamp, 'selected' to light at 6 volts dc, with a33 k resistor in series.' So, now you know how to make your own Seeburg Test Lamp. M100A - Calcoin conversion manual / WICO Conversion manual (right click to download - 7mb/4mb) to change your useless (the mid-1950s opinion of 78s) 78RPM M100A to a great 45RPM machine! These were from a company called Hudsons Bay Wholesale which operated 100's of Seeburg jukeboxes across Canada back in the the day.the author was Karl Jones. Great Seeburg resource guides! - The first PDF (click here) is for servicing SHP and TSA series amplifiers, the second PDF is Digital Troubleshooting the electronic selection system (black & grey boxes).
