For some reason, it regularly shocked the lead singer. Which, considering the reverb on these amps is nothing spectacular, this means that any guitar player looking for the Beta sound can easily acquire a Beta Bass instead of waiting around for the now more expensive Beta Lead. I replaced electrolitic caps with 50v to avoid fireworks inside the enclosure, used 50v 10uf caps for the charge pump as well. Or, may be used to engineer a modification to amps which have a toggle power switch switch, but don't offer a standby switch such as the Peavey Delta Blues, Fender® Blues Junior, etc. Hi, long time lurker first time poster here.
So don't take anything personally it read into it. Has 6 electrical terminals double pole, double throw. The same thing the bass guys do with ultra clean power amps. Glad to of been helpful, as I said for a while I was doing the same thing, but if you look at the layout you will notice how the legs of the trim pot are connected to the same row as the link that then connects to the Drain of the fet. With all due respect, it wouldn't have been difficult to do so had the creators of this layout intended as such. Great tones from them : Yea, thanks to the doom scene they have gone up.
Dynaco was a popular kit tube amp for high-end home stereo and had an extremely conservatively rated 60W mono power amp you used two for stereo, natch. Mackie ® part number 0033500. It basically kept him in a constant state of terror. E actually found this for me, deadstock, on eBay about 10 years ago. Get Genalex Gold Lion quality at almost half the cost. See below for a kit of two of these switches with screws included for refurbishing Fender® amps.
Controls are working, biased my J201 as recommended but it is a bit quiet. Switch only - see part number K-058 for the switch cap. Save 40% over the cost of the original Marshall switch. I'm not saying it's impossible, just improbable. In order for this switch to be installed on a vintage amp, the hole must be enlarged to 30mm. Even if he was not touching anything else.
Q3 was harder cause I had to use a 20k resistor in series with the 10k trimmer to get 5v at the drain, and even with that amount of resistance just could go down to 4. The only place I can mount one is inside top of head cabinet — open side up, This thing has an awsome sound now and the reverb replacement will complete the project. The diameter of this switch cap is smaller than the original round switch cap from Marshall® found on some of the early ValveState models. Note: This original version has no bias pot on the power amp, with distort control. Elation followed by dying a bit inside when he was told what was done to it. Here's a brief clip iPhone, sorry.
Bridge methods must be used. Very simple, but always sounds great. Assuming that is, if there is already an idea of doing different versions it might be slightly easier overall? Hartzell was bought out by Fender in the early 1980's and shelved. I'd love to have an orginal model T one day. Used in effects pedals, front panel controls, etc, including some Boss ® products.
I've always had this idea of building a few tube power amps and then building a whole fleet of rack pre amps. Used on channel control and drive boost switches on the front panel of the Fender® Hot Rod Deluxe, Hot Rod Deville, Blues Deluxe, Blues Deville, Blues Junior. Sunns weren't known for great tone, but they were loud. The other guitarist in my band has a beta lead combo that is loud as hell and sounds excellent. The forth full stack consists of two 4X12 cabs and a 1000S with verb and trem. The 22nf lower right corner cap is the bass cap I think, correct me if I´m wrong.
Sunn Schematics Sunn Schematics, Service Manuals and Owners Manuals Please read our page before ordering! I've done the usual internet searches and read what I can find in amp books. This was actually the first time I had all of it in the same location! Sorry for the sidetrack, but SunnBass's comment struck a chord with me. Wish I didn't sell mine!! I downgraded both 470k resistors to 100k in order to get more gain. Note: Includes original 1978 and updated 1979 version. Has 2 electrical terminals single pole, single throw. I had to totally replace it.
Anonymous Hi there, Is there a way that I could use this like a Ruby amp? You will not find a schematic for this in the forum, as just Ciaran and I have it. Change the power, standby, and ground switches on your Fender® at the same time, and save! I have been desperately trying to find one and have been trying to trace the schematic from a bassman schematic and layout to modify it in line with the Sunn schematic but I don't quite have the talent. Honestly, it's time everyone made the switch. Used on many Engl Amp models. Has 3 electrical terminals single pole, double throw. Original Fender® part number 002809100.
Thicker plates, improved heat dissipation, higher transconductance, and increased linearity are just some of the inherent aspects of the new Sovtek super 6550s. Used as the Enhance switch on the Fender® Bassman 25. Mids don´t do anything as well as bass, which just cuts the whole volume when set at zero when the treble pot is set to zero as well. Has 4 electrical terminals on back of switch. Has 3 electrical terminals single pole, double throw. Found in other British-made amplifiers and cabinets as well. Since then I have re-tubed and recapped it entirely, and it is really a fantastic amplifier.
