scans available of GEC application notes
Hi y'all:
I thought that some application GEC notes on KT77 and KT88 amplifiers and on preamnlifiers were worth saving. So I did some scans and put them into dropbox. The following links can be accessed publicly. There are 8 files for this one: http://dl.dropbox.com/u/14995214/GEC...or_KT77_01.jpg 16 files for this one: http://dl.dropbox.com/u/14995214/GEC...or_KT77_01.jpg and 18 files for the last one: http://dl.dropbox.com/u/14995214/GEC...or_KT77_01.jpg For downloading you just change ...01.jpg for ...02.jpg and so on. I'm too lazy to place all the individual links here. Just let me know if you can use it. Kind regards, Eike -- "Discipline may only mean a hundred men making the same mistake at the same minute" - G.

Kind regards, Eike The scans are very nice but they are so large they take Eternity to download, and I would think they'd be better if reduced to B&W .gif form maybe 200kB max to maintain full readablity.

Patrick Turner. That may happen later on or not at all, Pat. I cannot promise anything. Scanning B&W with originals so yellowish-brownish of various hue and tint due to the age and bad paper takes considerable effort and time. I'm short of time, that's why I made color scans. Kind regards, Eike |

Great post. Made me dig out my old blue cover booklet: The M-O Valve Co. Ltd. London, England. Genealex 'Audio Amplifiers' March, 1979 (Dist in the USA by EEV, Inc 7 Westchester Plaza, Elmsford, NY 10523) I got it when I scored a shineola load of tubes for almost - nothing.. Back then, 66/77/88's came with neat Lion screening and if you were lucky, a chart of how THAT tube tested. When it all ended, 88's could be bought at $8 USA ea per 100. When I bought my lot, 66/77/88's were ALL $5 ea per 100. People want to pay $20 now for the box. Other sell offs: When Celestion and Marshall designed the 'PowerCell' line of cabs, they had no idea the public wouldn't buy 1-12" cabs the size of 4-12" ones, esp with ugly future MoJo horn type looks. FEW of the cabs were made, but a few of the raw speakers were. I bought a pallet of them for $30 ea (thanks Steve). Huge magnet, 3" VC, 200 watts of GUITAR Celestion. WHY they don't make this today? When Marshall designed those 400 watt bass amps with 8 6550's, no one wanted them. I found a few, bought them for less then the power tubes costs. What is there behind the boxes, but about 15 sets of PT/OTs, unused. Cost...$10 per transformer.. (again, thanks Steve) Today, you can't SHIP them for that.. Alas, today..such deals are far gone... JJTj Can you show me a dream..? Can you show me one that's better then mine... Can you stand it in the cold light of day..? ...neither can I... |

I don't mean to be ungrateful for the work but 1) most of these are
available in the Audio Amateur book release from clean unyellowed prints and 2) I never bother with scans that aren't in the form of a complete .pdf volume anymore (DjViu was nice but appears dead now.) |
