Impact Amplifiers was started in London in 1963 by Don Mackrill and Laurie Naiff. and also had some music stores, Pan Music, Take Five and King Street Music Stores.
That being said he cannot for the life of him date the sax. Whats got him puzzled is the serial number starts with a letter; B21xx I believe. Links to pics below; you need to scroll down a little bit!Buescher, Martin, Orsi, and Kohlert (I think), and perhaps others.Below is their sign on the back of amps sold in Sweden. S-marked amps has the voltage selector removed, and a few fuses added for higher safety.It's missinng on my own Impact 60, and the Impact 100 never had any, since the 60 was the only model that got S-marked and approved for the Swedish market. The Impact 60 head was the most common and popular model.Recently I got me another scarce, English guitar amp, a Miles Platting V.100 from 1974. It has two Fender-styled preamps with a Marshall-style 100W power amp.
If you know anything about that brand, or want to know what I know about it, please send me an e-mail!
My own user name there is "6 10"Below is a copy from an English Bells Musical Instruments catalogue from about 1970/71, which was sent to me from the kind Selmer-enthusiast Tim Fletcher. (Take a look at his and Steve Russels nice Hofner site, which also contains a lot of information about Selmer, Watkins / Wem, Bird and some other amplifier brands.)

I have some pictures and schematics, as well as some copies from a couple of catalouges from the distributor out here: MILES PLATTING. Other vintage, British amps I have or had, is two Selmer Treble N' Bass 50, one MKII and one MKIII (both sold now), several Carlsbro 50 Top and a Carlsbro 100 Twin Channel.
I also have some Italian FBT tube amps, 150, 250 and 500-R2, as well as a few Swedish Hagstrm tube amps, 210, 310, 510, 620 and 840. If that's not where you came from, please make a visit at Plexi Palace, where there sometimes is some talk about Impact amps under the cathegory "Miscellaneous British Amplifiers".
Thanks to Don, I also got in tuch with the Swedish Impact distributor at the time.
