Marshall 1969 VINTAGE CAB, PRE ROLA SPEAKERS

Marshall vintage BASKAST, grondkast, BOTTOM niet ‘slanted’ daterend
van 1969, speakers dateren van 1968.
Basket Weave frontplaat. Denk Jimi Hendrix die toen ook Marshall BASkasten gebruikte.
Originele handvaten en dikkere houtstructuren dan latere kasten.
Kast was bij aankoop zeer slecht herbekleed en zelfs met rode verf overschilderd.
In de jaren 90 persoonlijk laten herbekleden met
toen voor handen zijnde Fender vinyl door de bekende Vlaamse versterkerhersteller en -specialist Yves Pexters omdat die erg leek op de originele Marshall-vinyl, maar toen toevallig besteld was.
Helaas zijn bij de herbekleding 2 zeer belangrijke cone-bedekkers met de belangrijke gegevens van de Pre-Rola speakers verloren gegaan,
Gelukkig zijn de speakercodes nog grotendeels intact en is er duidelijk geen hersoldering gebeurt.
Voor de kenner:

4 x 1968 PRE ROLA Celestion Thames Ditton Surrey G12M T1511 25WATTS 16OHms 75hz Pulsonic Cone bass response cone stamp speakers, in used condition, but not reconed.

T1511 (16 OHM)

Celestion greenback 55Hz G12M

T1511 is the 55hz version of the G12M speaker. It was the stock speaker in Marshall bass cabs (model 1935) from around mid 1967 until the very late 1970’s. They were not exclusive to Marshall as I had originally thought, but are pretty rare to find in anything other than Marshall.

Notice the wide band of doping on the front edge of the cone compared with the T1221.

Pre-rola period speakers will always have 75hz printed on the labels. Look for the white ‘102 014’ stamp on the cone and this verifies that it is the 55Hz cone. Only the later ‘Rola Ipswich’ labels with the speaker symbol, circa 1972 onwards, tend to have 55hz printed on them.

Note – this has been my experience with ALL pre-rola 55hz speaker models, not just T1511. At that time Celestion did not have separate labels made for every speaker model they produced. No 55Hz label seems to have existed then. Celestion would share labels between models and alter the information with small stickers when necessary. See the labelling for model T1440 below as another example of this.

T1511 was designed for bass but is a popular speaker with guitar players due to the different tonal characteristics compared with the T1221. It has less mid-range, and more of a scooped tone.

This is another classic Celestion greenback model crying out to be reissued.

The speaker date stamp is 19JA, which is a transitional (from gasket stamp to horizontal frame) I guess: 19 october 1968.

Correct me if i am wrong please about the details.

ONLY SERIOUS BIDDERS, PLEASE!!!!!
