The Amp Garage

Just got two of these chassis from this guy shipped for 40.00 they are just over 1/16" thick and come in a brushed finish.

Well it didn't link to the right thread, just scroll down to 19x8x2 chassis sale. He will make a 17x8x2 for the same price. Top quality

Well I aired it out good this afternoon for about three hours straight at mostly half to full and all I can say is ....!!!!OMFG. This amp makes playing effortless. I don't have to try as hard to let my emotions through into my playing. It will take a little getting use to but I love the finesse this...

Anyone see a problem with leaving the 1 ohm cathode resistors on the output tubes for biasing ?

You guys are after my heart here now. When they burn up just go buy another set.

I'd be concerned about using 6L6's in an Express. The plate voltages in an express are approaching max values for a 6L6. Hmmm, the Express puts out 395V plate / 380V screen, quite far from the rated 500V /450V of a 6L6GC. Anyway, voltage alone doesn't kill big bottles, current x voltage does : you ...

I'd be concerned about using 6L6's in an Express. The plate voltages in an express are approaching max values for a 6L6. Don't be surprised if they don't last too long. Just my $0.02 Steve Oh... Still would love to see some photos of the amp. I will post some amp porn first chance I get though she ...

Well I wired my Express up today as far as I could go (I am waiting on a multicap to come in). I couldn't stand it so I rigged some singles just to try it out. She came up nice with the obligatory plate lead swap to rid myself of the shrill and all voltages are within spec so what the heck, I fired ...

Thanks for the help and the advice.

EL84's draw 45 mA plate + 10 mA screen max in a typical Rocket-class amp, so a PPP with 4x output tubes and 3x ECC83's should be rated for 200 mA minimum (the amp is class AB, with only two EL84's drawing current above idle). Your 125 mA PT should be OK for a PP version (two EL84's). At this curren...

I'm adding up the current draw for the rocket because I'm trying to build one with what I have on hand and later on upgrade into the proper iron. So if I have it right each output tube is roughly 25 ma and each preamp tube is around 3 ma worst case. That would draw around 110 ma from the transformer...

My pilot light is fixed so it is not a problem. I set the bias pot at -43 v and tried it with tubes. Again no pilot light, the bulb limiter stayed bright for 15 seconds and the filaments were showing no signs of lighting up so i turned the amp off and again no charge. This part is key here guys for...

I've tried to register a couple of times with the same screename as I have here and never got on, so I have no idea what I'm missing ???

In this pick a cliff jack is used on the input. Cliff jacks are isolated from the chassis and require a seperate ground wire , which the builder installed. The metal switchcraft style jacks are grounded through the frame and do not require a seperate ground. If you refer to the amp layout in the fil...

I notice you're using the fender style switchcraft jacks. Are they the shorting type ? I just had a problem with a brand new set on a fender deluxe build. The shorting contact arm was weak and I got intermitent crackling and every now and then a high pitched wooshing sound out of them. It got so bad...
