Re: [AMRadio] Re: AM ?? Vince
On the Ampeg... My friend Steve had two of those heads and the matching six foot speaker cabinets... I'm glad you know about them because I have been call a nut for even mentioning them... no one remembers them... If you have ever been beside two of them ripping... you know all too well they are real... As for the Fender... yeah well... I keep mine because it was my first real amp and for no other reason... I was never impressed with any guitar amp designs... always too close to tolerance for me... I would be happier if the Fender had 807's... heh 73 vince ka1iic On Saturday 07 April 2007 17:00, [EMAIL PROTECTED] wrote: Hello Vince ! You said: BTW...

Re: [AMRadio] Re: AM ?? Vince
Yeah my friend Steve had two and used them for lead guitar...When he was home he had both of them against the wall in his 10x12 bedroom... He was big into blues... I remember one after noon me showing him 'The Bluegrass tune Wild Wood flower' using them... The entire neighborhood thought Steve had 'lost it'... great fun... heh 73 vince ka1iic On Sunday 08 April 2007 15:38, Daniel J Wright wrote: Vince Werber wrote: On the Ampeg...

Re: [AMRadio] Re: AM ?? Vince
Osss... I forgot this was the AM list... perhaps I could justify the guitar amp thing by mentioning me using a Class B modulator deck a pair of 5514's in fact as a output amp and using the Fender as a driver... I use an old military surplus plate transformer for the output transformer... that tranny was about a square foot in size and one of those real weird trannys... Maybe 760 volts center tapped with a bunch of low voltage outputs... I seemed to get a reasonable match of off one of them... can't remember which one but that tranny had a bunch of low voltage taps... 8, 17,24,36 volts things... It worked and didn't blow up... quite effective for what it was... 73 vince ka1iic __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.

Ah OK - the SVT DID use 6146es for one year - 1969. All of the ones I ever worked on were the types with 6550s, which I think covers the majority of them... Either amplifier is good for about 200 to 300 watts of audio. VERY nice when you need a little extra kick in the pants on stage! They still make the SVT CL model with 6550s at 300 watts. I worked on a number of those as well as the larger Sunn power amplifiers, Fender 400 watt (claimed) amplifiers and the like. I think Acoustic had some chunky models that would really churn out some audio power too - but they were all squalid state. HiWatt lived up to their name and built some with Six KT88s Ampeg claims that their SVT-8 head will deliver 2500 watts RMS. Again it's squalid state, but how's THAT for rattling the walls? Don't practice on that one at home when the neighbors are in! __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
Re: [AMRadio] Re: AM ?? Vince
Well most of the time when I do operate I do AM... with an old Collins 32V1 in fact. When I must do SSB I use my old NC-183 with a product detector that I stuffed under the chassis and from there I EQ the audio out to smooth it out I have to round off the peaks because of my hearing being messed up heh perhaps I would be more correct to say I mellow the signal :-) BTW...

On Saturday 07 April 2007 06:03, [EMAIL PROTECTED] wrote: Hello ! Vince I can certainly understand the guitar amps ! Can still hear them myself. :( But what AM all comes down to is that the human ear, no matter how abused, still is ultimately critical of the phase accuracy of received sound. Especially in the voice range. Some of this is due to the brains function of locating position by phase difference between the ears. Whenever an audio signal is bandpassed or EQ'd in any way there are often serious phase shifts created. So the broader and flatter an audio signal and the further outside of normal hearing range the filtering is kept the easier it is to listen to and more musical due to the proper phase alignment of both higher and lower harmonics of the sound. I am primarily refering to analog audio here. Digi is another can o worms.
