Seeburg LPC480 45TASU1 Auto Speed Control Recapped

The Seeburg 45TASU1 auto speed control is fairly simple, yet is key to the functioning of your LPC 480. If the 45 RPM records play too slow, or play ok for a while then sound sluggish, or if they don’t play at all, it’s probably that the 45TASU1 needs rebuilding. The big oval aluminum capacitor is most likely the cause of erratic 45 record speed problems, but while that’s being replaced, it’s best to replace the other capacitors. There’s only a few. If the oval aluminum cap is original, it should be replaced whether it’s good or bad, because it will go bad.

Seeburg LPC480 TSA1 Amp Recapped

Changed out ALL the Electrolytics and paper caps on the Seeburg TSA1. Newer caps are physically much smaller than the originals. Mounting can be a challenge due to their smaller size making lead lengths a little short.

I usaully clip the old leads close to the cap, that way I have something to attach to. Sometimes you need to remove the oxidation from wires to get a good solder joint. If there’s a nearby unused terminal lug, it can be used to attach and help support the new components.

Nice thing about the TSA1 amp is it can be operated completely removed from the cabinet. I hooked it up to my home stereo speakers. Man it really cranks!

Here’s the recapped amp:

Seeburg LPC480 Prepping for Restoration (Part 2)

Before powering up a non-working Jukebox, the Jukebox needs to have everything Re-Capped . Re-Capping is the process of replacing ALL the Electrolytic and Paper (and if any Wax) capacitors. Electrolytics are polarized capacitors. Sometimes they’re in an aluminum “can”, sometimes wrapped in cardboard or a clear plastic sleeve. In the picture below, there’s one large aluminum capacitor, three medium-size 1200-µf  capacitors and various smaller capacitors (you can see one marked “Germany”).  These ALL get replaced. It takes a bit of dexterity and soldering skills to get into some of the tight places. This amplifier, if I counted right, has 17 electrolytics. The replacement capacitors are physically much smaller and reaching the solder points is an art unto itself. It is imperative that the new capacitors are installed with the correct polarity, or things go horribly wrong! The Speed Control and Tormac Control Center also need to be Re-Capped.

Seeburg LPC-480 Restoration Project Part-1

Follow along as I restore my non-working Seeburg LPC-480. Most of what I’ll cover also applies to the LPC-1 Seeburg Jukebox.

Most jukeboxes are too heavy to economically ship. They can weigh over 300 pounds! So I drove to pick up my Seeburg project.

Here is the as-is where-is picture before pickup:
