Porr FS - Ampeg SVT T - Amps - Harmony Central Foton
Ampeg rewrote the book on high power amplification in with the introduction of the SVT. Sure, they had a few other good products, in-between changing ownership as numerously as Michael Jackson was changing his nose. So in the late eighties, they just started throwing the SVT name around like baby batter at a bukkake convention. And hence, the SVTT, produced from featuring no valves at all. One night in it took a dump.
Or maybe I took a dump. Did I have the wrong speaker set up? Was it just old? It took me a lot of learning over seven years, but I finally got this tubeless, sad sack out of the closet and farting again. When I first tried to get this amp fixed, I called around to a mess of techs.
It was refused. Safety first: like any amp, working on one can kill you. Some are designed to do this, some not. Luckily, the SVTT does discharge itself and rather quickly in about seconds. I tested it along the 69 volt power rails coming from the bridge rectifier and to ground using my multimeter until it read zero.
I made a visual check. When this amp fried, it made a popping noise and the tragic smell of a baby burning emanated from the insides. R28, R29, and the T power relay were done for. I sourced the resistors locally and ordered the relay from Mouser Electronics. The relay plopped right in. Nära Kryssning 2019 the resistors, I scraped away as much carbon residue from the toasted ones as I could and carefully taped electrical tape over the PCB wound.
Carbon residue from something blowing up can conduct electricity and needs to be cleared for new parts. Heady shit. Instead of me dying, though, I was making my amp better. Not by a long shot. I fired up the amp, the relay clicked, and… nothing. No sound. I ran a signal out of the pre-amp to another amp. Whatever fried those components was sure to have done some other damage, I thought. I took out the board, I tested the transistors, power transistors, and I went through all the test points indicated in the schematic.
Some people on the www. The headphone out of an iPod gives you just enough signal to make this possible. I thought it was pointless, but when I cranked the amp, I could just hear the tiniest squeal coming out of the speaker.
Are you fucking kidding me? I know for sure I fried one of the ICs in my clumsiness. I replaced the shit jacks with new ones. What other damage did I do? Desperation set in. I took it out of the circuit.
It was leaking so I replaced it. And that set me off. I ordered every kind of diode that was in the SVTT schematic. While waiting for snail mail, I tested every diode while it was in circuit. But sometimes you do. By process of elimination, I weeded out what were definitely healthy diodes in my amp and marked the suspected ones. I then desoldered a leg of each suspected Ampeg Svt 100t and tested it out of circuit.
I replaced them. I tweaked that variable resistor just a touch to get a couple test points within tolerances indicated on the schematic Netvideogirls Tube. My amp worked. After five years of waiting dormant, then two years of my starting Antonella Nude giving up again fixing it, this fucker works again.
Besides replacing a few missing Ampeg Svt 100t with OEM parts from www. I detached the cord from the spade plugs on the inside of the amp. I used a Dremel to cut a new hole for an AC socket-in which I attached with some size 4 black Ampeg Svt 100t metal screws and speed nuts. I originally considered fixing this amp, the gods willing, and Ampeg Svt 100t selling it. Plus, quite honestly, the resale value for the SVTT is complete and utter dog shit. Last time this Ampeg Svt 100t was working was the dark age of P.
Someone did upload this old video of a hooded menace rocking the SVTT, however. It sounds good, if you can make it past the shit talking intro. If Nurshath Dulal still have a copy of the amp schematic, I would love to have a copy. I am trying to fix a svtt with much reduce output. Still loud but not where it was once.
Proceed with caution!!! Daynia can kill you. If you do have success, however, please come back and comment on what the problem and the solution was so you might help any other people reading this. I have the same amp, which has some problems in Power amp section.
Already, for example, I do not have the 69V you talk about I really need to have the schematic Ampeg Svt 100t make further progress.
Hello there, I would also like a copy of the schematic. Thank you very much. Hi, great info you got here! Much Youporn Teen if you could please email it to me, thanks in advance! Hi Can you give schematic of svtt pleasemy problem is a low distortion of hz frequency … Mail: stef72lemarchand gmail. Thank you so much for this write up! The previous owner Mistress Thailand Massage the line out works, but not the power amp section, yay!

Previous Post Ghoulection Transmission Twelve. Thank You. Could you help me out and send me the Schematic, I have not been able to find it anywhere. Thanks, Grant. Hi there Would love a copy of the schematic please sir. Thanks in advance Dave. Leave a Reply Cancel reply Your email address will Ampeg Svt 100t be published.

sv-r- T is on, the Gain control (3) will adjust the amount of limiting and sustain. The 'Master" control (11) is used to set the overall listening level of the SVT-IOOT Balanced Line Out Level (13) This control adjusts the output level of the Balanced and Un-balanced line output jacks (24&25) on the rear panel of the SVT .
21/11/ · I purchased a SVTT at a pawnshop for $ It is a w combo amp with two 8" speakers and a piezo tweeter. The amp section appears to be the same set of electronics as a B15T.
This is a watt solid state Ampeg bass amp with 2 - 8 inch speakers recently replaced. Made around Line out Volume. You can post now and register later.
