6L6 project idea needed

[jestaudio]

typical me but having preety much finished my marshall style build i have a latfully recievedoad of parts left over, so i,m looking at using up some of these bits, i have a toirodal tranny with 240-0-240 outs plus heaters, a 30 watt OT, choke and best of all NOS winged C 6l6s, so i,m looking at a low power amp, possibly fender flavoured, single channel TMB stack and tayloured for pedals.
Any ideas are greatfully recieved

Big bottled Rocket. Loves pedals and chimes to all get up.

so a rocket preamp with a 6l6 power section, i suppose i can use something like the hot cat power section phase invertor back wards

The only thing I change in my octal rockets is the v1a 220k plate resistor to 120k for less gain and keep things clean.

Add two octal sockets with 470R screens.

A Rocket is the bright channel of a Vox AC30 or Fender 5F6A.

you got a scheme or layout for that , give a starting point, voltages would be usefull as well

Search the trainwreck forum for big bottle rocket. Normster and rawnster have done layouts I believe. I use RJ's power supply layout from his Rockster I believe.

There is a layout in here. Just omit the reverb unless you want it.

Here is normster reverb version.

If you dig deep enough and really look at the schematic of a Rocket preamp mated to a 6L6 power amp, it starts to look amazingly similar to a 59' Bassman... eluded to by Mark Fowler earlier in this thread.

They are really versatile since you can tune them toward the clean or the dirty side with a few tweaks here and there and the clean versions love pedals. If you keep the cathode bias technology of the Rocket, they still sound Rocketish but the big bottles give them more of everything. That also lets you swap in a variety of output tubes, most of which sound great. I found I could tube swap from 6K6's to KT88's with minimal adjustment to the bias resistance (if your power tranny can handle the heaters).

With your 240-0-240 power transformer I'll be curious what kind of headroom you'll get. I'm sure it will be enough to be loud and still clean but you should get some really great sounding crunch coming on as the db's start to climb.

YMMV

I took yours and others advice here and decided to convert my 6AQ5 Rocket build into a 5F6A with 6L6's. The amp turned out fantastic but pretty quickly into this build I realized that almost every component is a different value. I ended up completely starting from scratch (i.e. gutting the chassis, board, sockets and pots) and like I said I ended up with a really nice build. I can quickly see the similarities between the Rockster and the Bassman but the Rocket is a different beast (but nonetheless a really great sounding beast).

to be honest i,m not desperatly bothered abot the head room, i,m more interested in seeing what i can do with the components on hand, i don,t suppose anyone has a layout for this scheme, saves me trying to do it

Fair enough - the circuit looks the similar with an expectation that sonic results can be drastically different. Just considering the transformer designs typically used in each build, that's not a stretch before you start throughing different value electronics at it. YMMV

Ken Fischer would be ever so proud!

Here is what I have been developing over the past few years - there are some other good ones out there as well. Don't take the component values off the the layout, refer back to the schematic.

The reverb version has received the most attention over the past couple years... maybe a good addition but it can be easily done post fact.

thankyou muchly RJ, that gives me a good starting point, i won't be using the tube rec, i thimk the diode rec should give me a bit more voltage to play with, plus i can always adjust the dropping string to compensate

[RJ Guitars]

OK - one more version then, "the "Ripster" - something new that needs to be scrutinized and built before anybody can say it's a good idea or not. Same basic chassis and layout as the Rockster only use a slightly modified PS board and forget the tube rectifier. The choke is still in there though...
