The Amp Garage

i am looking for ways to expand my new build a bit. it is not nearly as loud as i thought it would be, and it gets dirty very fast. i would like to get more volume at least. every tw i have played is a good bit louder then my build. after looking at the different tw schematics and layouts i notice t...

welcome i would get a kit and save yourself some trouble. rjguitars.com is a good one to look at he has everything you would need for a tw build. you should get good parts, saving $20-30 on components will fall short of a 'decent amp' and in the long run could stand to give you more problems then it...

I tested my amp through a 16ohm cabinet and thought I may have wired the OT wrong on the switch. After switching through what I thought I wired as 4/8/16 they all seem to be the same volume with no reduction at all. I used the 3 way switch from hoffman here : [img:560:266]http://www.el34world.com/ch...

It is the center tap for the low voltage winding and the 6.3v leads. they melted but the smoke surely came from the PT.

So i fired up my rockster with 6l6s and a 5u4 and it started to smoke. I unplugged quick and took out the tubes and fired her again, smoke. I took the power supply board up and noticed the CT for the filaments was melted, then the filament taps themselves were melted. So I started over, figuring the...

My Stangray has a simple loop that works but I never use it because I don't run outboard gear anymore. You can add an effects loop if you like sure. The Rocket doesn't need gain pedals but if you wanted to color the sound with modulation rack or pedals sure. When you said D type loop I was thinking...

Just my opinion but an amp like the Rocket doesn't need a loop. When cranked, all the distortion happens so late in the circuit that it will occur after just about any loop you use so you haven't helped anything by adding a loop. Generally, effects loops are designed so the distortion occurs before...

I actually just bought this from him and thats what he had sent to me, also saying it was unverified, so with that correction this layout seems like it should work quite well. does using the filament taps for the lamp scare anyone at all? transformer says 6.3@4A i figure 2.6A from the kt66 pair and ...

I am using the documentation attached below.

so the lower primary gives me more plate voltage/more headroom?

i want to say before i start that I want to use a 6.3v lamp instead of the 120v, I figure I should have around 800ma left of current for the lamp (maybe i am wrong?) as i began to wire i started to confuse myself a little: [IMG:1600:1200]http://i53.tinypic.com/2wgspqe.jpg[/img] i noticed in the layo...

I built a probe and did the audio test on all the joints. Audio passes through all of them, including the input. The pots were acting sort of funny in terms of quick rise in volume when turned up, but I guess that is the power coming form the iPod? the guitar signal breaks up like a bad fuzz pedal o...

After stepping away from this for a few days, I went ahead and did the test structo suggested, and found the OD section to be non responsive. I decided to simplify and take out the relays, and that seemed to be part of the problem. Everything "pops". Now all the pots seem to be doing something, but ...

I spent all night taking everything apart and rewiring. The hum has seemed to disappear but I am still getting zero signal coming through. I know for a fact everything is wired up like the layout. Everything is grounded correctly, tubes all getting the proper voltage, I even rebuilt the phase invert...

I did get the voltage thing situated and all the voltages run smoothly when testing. I just can't get sound. there is a low volume hum oscillation still. The hum changes pitch when I check the voltage on the phase inverters, and when I change the setting on the trim pot. a short possibly? I'll check...

I am betting you have something wrong with the filament wiring. You said they weren't lit? If the heaters aren't working you'll get big volts. Check your filament grounding scheme. Did you use resistors or a true CT? The were lit at first, then they were not. I may not have the filaments wired corr...
