Re: It's Coming...... PICS

Oh, and another thing: You know how running amp thru an attenuator at high levels gives a nasty buzzy tone???

With the Strat, it gets a nice fuzz tone to it...probably gonna be killer with the 'Bird's mini-hums

The chassis fits inside the headbox perfectly...lots of room for the KTs. The vents were a good idea, but only one is placed directly over a tube & I noticed the box itself was warm where the other tube was. Maybe a good idea for the next one would be putting a vent all the way across. Probably no big deal but you never know.

I put multiple layers of metal foil tape on the underside of the headbox to keep the tolex from getting damaged. To put vents in the top is going to add costs, but after seeing yours, I'm checking into it.

:
Hey...I meant to ask: the EL34/KT66 switch....does that lower the plate voltage or what exactly does it do? I assume a rebias is still needed, right???

All this does is put a different value resistor into the bias loop. I based the value on a few sets of EL34's and KT66's I have here. The only bias pots, i can find, that allow for adjustment from both sides of the chassis are 10K. That would be a lot better if it was 50K or 100K. I couild go to a different adjustment pot value, but that would force you to pull the chassis whenever you wanted to adjust the bias.

The toggle sitch I used is kocated such that if a particular set of EL34's are outside the bias range, you can go in ans easily put in a different value resistor. Easy access for a tech.

The only other issue is the output impedance will be off with EL34's. The OT has 4 wires coming off it. With KT66, the wires correspond to 32, 16, 8, 4. With EL34', those same wires are 16, 8, 4, 2 ohms. So, you'll need to set the amp to 16 ohms IF you are running EL34's and an 8 ohm cab. Or, if you go to EL34's fulltime, a tech can go in and move the wires on the impedance selector switch. The wire that corresponds to 32ohm-KT66/16ohm-EL34 is cut to proper length and terminated such that it cannot make any contact w/ the chassis and short out.

I'll email you the manual later.

COOL....and I meant to say nice touch with the printed out "Made for" & serial number lables

I think it was the Hiwatt I had that had this, but I think the best bet is on the top rear of the box, instead of 2 little vents, route out section & use the same vent screening as on the back, on the top.

Did that make sense???

I couldn't find a top view, but you can see what I mean in this pic:



Look behind the handle....see the routed out area???

Ok Terry, enough gibber-gabberish and more pics and clips

Glad you got it in safely

Glad you got it in safely

For the record, it was packed to withstand an elephant. Armotron's amp had taken a drop that never dinged the head, just shearing forces that caused the backplate to crack and the plastic fuseholder to break. It was packed well, with formfitting foam all around, hence the fact the enclosure was not damaged.

6' foot or greater fall on its end would have had the same results had it been packed in an ATA-approved flight case.

I just wanted to clarify.
