Just finished my Express cab this week and thought you might get a kick out of a quick photo. The cab is oak stained with a chestnut stain with 2 semi-gloss clear coats. Not bad for a rush job :

Ron wrote:Vaughn, did you use the polyester ODs or the polystyrene (715 or 716) types?

I used the 6PS type.

The Moose/Hayboer transformers fit the mounting holes perfectly. The problem is getting the wires from the power transformer inside the chassis, since they originate from only one side of the PT. I cut most of the unused leads (for example, rectifier filaments and low-voltage B+) so that I did not ...

It's the Ceriatone aluminium chassis.

The fuse is in series with the power transformer primary and the on/off switch....so, technically speaking, it really doesn't matter which side of the line you put it on.

....but I couldn't resist making some changes along the way. I started with Nik's boards and chassis, and Moose transformers. Then I: 1) Upgraded the in & out jacks. 2) Upgraded the coupling caps to orange drops. 3) Built a Sprague filter cap module board that's secured to the chassis with two of th...

Actually, a few years ago I assembled a 5E3 so I have a little more knowledge than I let on. I know enough not to get electrocuted which is most important. Thanks for your response. I'll post a pic of the impedence selector as requested. In regards to my first question, I was asking where the lead ...

Does the stock Express bias circuit have enough bias range for 6L6's?

I just received my transformers from Moose. Be patient...he told me that he has recently moved and has been out of town quite a bit these days on a work project. He'll probably get back to you as his schedule permits.

Anxiously awaiting for my chassis & tag boards to arrive....but Nik says he recently ran out of tag board turrets .

Just took a quick glance at your photos and it appears that you don't have a needed ground wire attached to the + side of the bias supply electrolytics. With the bias supply filter caps not grounded, this would create hum at the amps output.

I'm starting my Express build shortly and I'm going to try using plastic cable ties to hold the filter caps in place. I have some small plastic chassis mount cable tie brackets that are made for this purpose which should work nicely without all the goop. So we'll see how it goes when I get that far ...

Finally found Moose....FYI, he's out of town and should be back some time next week.

Try contacting Moose through his webpage at toneslut.com. I might be wrong but I think I remember him saying he was going to be out of town for a short period. But I know for a fact that when you do hook up with him he'll have the goods as far as Trannys are concerned. Yup, I originally tried throu...

Hi Rob. I've owned a few Komets and the fast/gradual switch changes the feel & gain of the amp. It's difficult to put into words but you know it when you hear/play the amp. It's basically switches in/out a tap on one of the preamp stages plate load resistor but, for something that simple, it has a d...
