Magnavox Astro Sonic Console

Hello:
My needle is skipping on this recently purchased console. What information do you need to assist me? Is there a weight adjustment on the tone arm? Also what is proper needle replacement

Also loudness dial creates loud discharge sound until it is set, then all is well. Afraid this sound will damage speaker. Would a shot of compressed air clear this up?

MODEL 1rp657----Year made ????

Thanks, Rich----Beginner status

Rich,
A close-up photo of the needle/cartridge to John at www.needles4turntables.com will probably get you the correct needle--I would suspect that the problem with the skipping and the volume control is dirt. You will probably need to find someone familiar with the changer to dis-assemble/clean/re-lube it. The volume control, if you can reach it, should be sprayed with a cleaner, as it too, is dirty.

Yes, definitely the 60's, maybe around 1966. I have a 1966 brochure that features alot of the 1rp650's models but yours wasn't listed. I also noticed that the last digit differentiates the base/styling of the model. I was hoping to find a 1rp656 or 1rp658 on either side of your number. Some have a solid base all the way across, while the similar model will have small legs/feet. Still basically the same cabinet.

Oh, take off the back and look for the little date stickers on the receiver and amp. There may also be a date sticker on the under side of the turntable. Look for something like "10/65" (October, 1965). You can also find your model numbers if it is not stenciled on the amp, like A575-01-00. The turntable might be W620-xx-xx

When it comes time for repairs, you have to treat each section separately. Get the number off the cartridge before buying a new needle (might be a Magnavox/ElectroVoice/Astatic number), get the numbers off the receiver/amp before buying a schematic, etc. That 1rp657 only applies to the cabinet and run number. I have two identical cabinets with similar 620 series turntables (different platters) but different receivers. One is from 1966 and the other from 1968. --BB
