Beogram 4002: New Project From Houston

I get to switch gears from Beomaster restorations back to a Beogram project next. I love working on both so either way it is a treat for me. A gentleman from Houston brought me a couple of Beogram 4002 Type 5513 turntables he had acquired some years ago. Eventually they began to age and stop functioning correctly.  Like most Beogram 4002 owners he found that he missed playing vinyl records on them so he had to get them restored.  I am lucky enough to receive the task and look forward to getting these back 100% working again.

One at a time though.

These were functioning well for the owner not too long ago so the Beograms are in decent shape. Here is the first Beogram turntable opened up.






















I already removed the DC platter motors back in March and sent them to Beolover for a full restoration. I have those motors back and they have been waiting for the rest of the Beogram restoration to catch up.

There are a few areas inside this Beogram where rust is starting to look bad. I will clean those up and put a stop to the rust. 

The Beogram phono DIN plug is badly corroded as well and the best solution there is to replace it.






















Here are a couple of pictures of some of the chassis components that have rust.























Interestingly this Beogram 4002 is one of the rare few I have seen where the plastic transport bushings around the floating suspension locking screw are still intact. They are still soft and in good shape. Most of the units I see have brittle bushings that have cracked and are in a million little pieces scattered throughout the Beogram. I will treat the bushings with some plastic restoration fluid that will keep them from drying out.






















The main circuit board looks in great shape. No signs of heat stress or corrosion there.






















The tangential arm assembly also looks to be in good condition. 






















Recapping the main board, replacing relays and speed trimmers along with cleaning and adjusting the tonearm mechanics should get this turntable back to working the way it was designed. The restored platter motor along with the replacement of the trimmers and speed indicator lamps (with Beolover's LED replacement modules) will have this Beogram spinning vinyl better than ever.

Time to get to work.
