Vinyl: SOCIAL DISTORTION - Ultra Rare METAL MOTHER STAMPERS For 1st POSH BOY 45 OC Punk THE ORIG METAL PARTS FOR THEIR FIRST RECORD - PLAYABLE!
For an indie label like Posh Boy, one metal 'mother' (essentially a mold of the record to be pressed) was made for each side of the record, from which stampers were made to press records. Stampers wear out eventually and are discarded, but the mother can be used many times to create new stampers as more batches of records are needed. So these mothers were used to manufacture each pressing of Social D's debut single. They have dates stamped on the covers, indicating each time they were used to create stampers for the single; the earliest being Sept 28, 1981 and the latest being Nov. 1 1983.
And mothers can be played on a turntable, to insure the transfer is correct and the stampers will make perfect records. The hole in the mother is smaller than a standard turntable spindle, but you can balance them on top of the spindle and play them--as we have these--and they sound incredible.
These are in beautiful condition, each in its original sleeve. Each measures approximately 10" in diameter. The matrix numbers are PBS 11A L8884 and PBS 11B L8884x.
For those not familiar with how records are pressed, we have copied the explanation below from "The Audio Class Newsletter"--since Ebay no longer permits links, we apologize to TACN for borrowing their content.
The manufacturing process starts with the lacquer (or acetate) disc created in the cutting room. This is too delicate even to play without damage and needs toughening up. So the lacquer disc is coated with silver, which makes it conductive for the next process, which is electroplating with nickel. The nickel is then separated from the lacquer, giving a disc with ridges where the grooves would normally be - a 'negative' copy. Even though it is made of metal, it is too delicate to use to make pressings. This disc is known as the 'master' and there is only one. The next stage is the 'mother'. This is made from the master by a similar process of electroplating. It is feasible to create up to around four mothers, but for the highest quality recordings this is restricted to two. The mother has grooves once again and is playable. From the mother, 'stampers' are produced - up to six from each mother. Once again these are negatives, and are given a smooth chromium surface. The stampers, two per record, are placed in presses and heated with steam before clamping down onto a cake of vinyl raw material. The result is a 'pressing' which after trimming and packaging is the record that is sold in the shops or played on the DJ's turntable.
A pair of truly museum quality OC Punk and Social Distortion artifacts.
We grade all records visually, cover first, then disc; using the abbreviations M / NM / EX / VG with + and -. We try to describe everything as accurately as possible, and spot check any vinyl flaw that looks like it might make a sound. We regularly receive praise for our grading, but as all grading is subjective, we are happy to give a full refund for anything you aren't happy with no questions asked.
Unlike some eBay sellers, we don't feel the need to hype records by including long reviews or albums, quoting lyrics, making up arcane variations. We just grade accurately, describe any flaw, and sell only high quality rare records in fine condition.
