My S&M was lacking sparkle and, difficult to describe it, but 'tight' seems a good word to me. It took many hours to loosen up and develop a nice tone. I found the OD channel too bright and the mods (a combination of Jack Zucker and Pickmaster mods) I've done have tamed that nicely, but thats what the OD EQ stack if for on the HRM so I reckon, give it a burn in of at least 24 hours continuous running (leave it on with normal settings) and then come back to it.

I'm not sure about your speakers but before you get in to doing any mods, borrow a g12-65 cab if you can, just to see what the difference is.

If the bias had drifted so badly out it sounds like you have a duff component somewhere. I'd email Nik. He be able to give you better suggestions for investigation than I can.

I'm assuming thats with no effects in the Klein loop. I'd check the input voltage first.

Then the bias on the FET. This is what Nik emailed me about it

You can check between the pin nearest to the filter caps, and the middle pin.
 
It's 22V

Hope thats of some use. Other than that has yours got the 10r resisitor and zener diode mod to protect the chip? Unfortunately Nik can't publish the layout but does your power supply board look like the ones in the website photos? This is the old layout. It should look like the photo below. Some people have managed to damage the chip with the old layout.

Got rather a few too many projects on the go at the moment to take on any more! Still finishing the 2x12 for the OTS then I want a 1x15 extension cab for my DC-30, plus I've a Warmoth strat project to finish (body needs re-lacquering).... the list  goes on(not including the fairly high priority Marshall clone or possibly the TW Express on the wishlist).

I'm looking to get a compressor pedal and thought this would be a good place to ask for opinions. We're all here because tone is important to us! 

So my criteria are, very light to moderate compression coupled with transparency (no colouring of) of tone. Must have a true bypass. Ideally in a small box as my pedal board layout won't allow for many more.

Thanks guys.

And did you see anything of that OTS SE by any chance?

Some pics

Just doen my DC-30 with copper foil sheet. Works very well indeed.

Just got the amp back from Shane Dolman. Powerscaling installed. Initial impressions are good. Powerscaling is better than the master volume by a good bit. It does lose some tone when scaling the volume right back but thats not really what I want it to do, just to ease off the volume levels of thios very loud amp.

Yeah a stain to match the Tele would be nice. Chestnut do a range of high intensity primary colour woodstains, though I guess Maple won't absorb that much so you'd have to spray with lacquer with the stain added to it, then it becomes vulnerable to dings just like  a guitar. Shame to cover the lovely wood grain with tolex though.

C'mon Mitch, lets see some pics!

Very nice indeed.

Forget the ground.

Tip = red wire= positive terminal on speaker. (actually the red bit is not imperative, you can use any wire colour, but tip goes to +ve) Sleeve= black wire= negative terminal

Yes 8ohms

EL34's not El84's. You could never put 9pin El84's in the OTS's 8pin sockets and I said they didn't sound very different to 6L6's.

Have to agree with wyatt, OTS with 6L6's is very little different to OTS with El34's. You wont change the character of an amp with different tubes, just do a little fine tuning, getting a little more or less of what you like/don't like.

For the OD channel V2 is what you need to mess around with, you can get some quite different sounds by changing to 5751's Ay7's or whatever. Downside is that you will lose gain on OD channel and you might not be able to marry clean and OD channel volumes without changing V1 aswell, and then you lose overall volume and you'll not get your powertubes driving the same if you turn it up. Lots to play with, but its pretty good out of the box (after a good burn in), pedals are where its at if you want very different sounds and the clean channel does these really well. Pedals only work OK ish on OD channel if its not set to a highish gain already.
