Rocker 30 circuit

[Jondog]

Had the day off, I got bored so I did this. This is just the Natural Channel into the Phase inverter. Didn't have time to do the Dirty. I also did the power amp but I haven't drawn it on the PC yet. Also not guaranteeing it's 100% accurate, so if you see something wrong, feel free to correct me!

Not shown but R45 runs parallel with R46 from the Natural channel schematic into C25 to the P.I. Thought I should mention.

Thank you! I can FINALLY sleep at night now. Whew.

If you happened to have copied these or printed them before today, take another look as I've updated some of the resistor values. Have trouble with brown and red colors sometimes! I've also done the power supply section, but haven't drawn it up neatly yet. Struggling a bit with the relay switching though, does some weird things which is difficult to trace and I'm not that experienced.

Hi everyone,

this is my first post on this board.

Looking at the schem, some things are weird:

- R41 (slope reistor) can't be 1.1k, it should be much higher.
- RV5 I would expect 250k for Treble.
- RV4 is Bass and RV3 is Mid, also exchange the values.

Cheers,
Kell

Hi, welcome and thanks. Must of made a typo on the treble pot, supposed to be 250k like you say. Good eye with r41, should be 22k, that would be my red/brown trouble kicking in!. But rv3 bass and rv4 mid are the correct positions for bass and mid.

Sorry,

but the pot in the middle wired as shunt is a bass control. The other one below with its wiper connected to C31 is the mid control. So it should read:
RV4: Bass – 500kΩ
RV5: Mid – 25KΩ

I think where the confusion is, is that Ive labelled it wrong. Rv4 25k mid should be the bottom one, rv3 500k the middle.

[kell]

RV3: Bass – 500kΩ
RV4: Mid – 25KΩ

The labels in your schematics should be corrected, too.

Will do! Glad you took notice!

Do you plan to mod something, or is this just for reference?

I've done a couple mods to my Rocker before I did this and wished I had schematics. More less reference I guess. You can get schematics for many Oranges but the Rocker isn't one thats readily available on the net and Orange won't give them out. I've asked and so have many others! I don't know why, many amp companies include them in the manuals. I just decided to try and sort it out, maybe a help to others. Tracing the circuits for each preamp and the poweramp wasn't too hard, alot of back and forth. Looking at other Orange schematics helped a bit too as there are some similarities. The Rocker is it's own beast though, unlike the newer Oranges which all seem to copy preamps (mainly the Rockerverb), tonestacks and poweramps and do mix and matches to create a new model, even use the same PCB. I don't know of another Orange like the Rocker internally. Do you know much about relays? Having a bit of trouble with those for the channel switching. Have a rough idea of how it's wired but not sure as it's not like the AD series or the Rockerverb. I know it grounds one channel out, while the other is engaged and I think Relay 1 is after the Dirty gain pot, rather then before the input resistor on the dirty channel as I've labeled it. Also, if you know about the negative feed have a look at what I have labeled as that. Nothing states thats what it is, but according to the Rockerverb schematic, thats what it looks like.
