Dumb questions round 2 ...

OK. The Tweed deluxe amp kit (a head) I bought assembled came just before I left town for over a week. I came home today and had a chance to hook it up. I played it with a 1x12 open back with a Jensen c12N and a closed 2x12 with V30's. It seems to be working great. I have 2 issues I would like a little clarification on ...

1.) When playing in the distortion range (starts early with this amp) when I let a power chord (or note) ring until the sustain drops it off there is a slight rattle like sound in the amp. It seems like it may be a tube rattle, but tapping the tubes does not seem to alter it a lot. Anyone ever hit this before (it seems more pronounces in the upper frequencies).

2.) Of the 4 inputs, I thought 2 were bright and 2 were "normal". However, when I plug my guitar into either of the lower pain, then simply plug a jumper courd into the same side upper (without the other end plugged into anything) there seems to be an increase in volume. I assume this is supposed to do that, so is there also a high and low and well and bright and normal on these amps as well?

Sorry for my ignorance.

Bruce /Mission Amps	Who's kit it is? Maybe you missed something in the input jack layout. Bruce

slowblues	If you plug into the high input you run through to 68k's parallel gives 34k's in, 1m ground, If you plug into low input your going through 1 68k in, one 68k to ground, if you plug a dummy into the high while playing into the low you disconect the 68k to ground soooo you have 68k in 1m to ground so with the dummy there will be a volume increse. (I am guessing at the circuit) slow.

Thanks for the thoughts folks! It gave me what I needed to know.

Slowblues- This was it ... and it appears to be the circut. Thanks. The only change from an origional 5E3 is the ground drop is turned into a standby, and the extension cab connection is left out.

Bruce at Mission - I do not know who's kit is was, or if it was a freeform built kit (I suspect the latter) using a 5E3 diagram. It sounded to me like the builder knew what he was doing and ordered the parts he needed as he went along. The final product looks and sounds good in the chas alone. Well, save the little electrical fizzy soundning thing as the distortion tails off when I hold a power chord. This appears to me to be a tube issue though as it goes away as everything heats up (but what do I know), so after it warms up it is working great. I seem to remember having this issue with a set of tubes I had in another amp. But, as I say, what do I know!

It is in a non-coventional chas. so I will build a cab for it. I will probably mate it with my 1x12 home built in white blonde, or the 2x12 Avatar I have. Itf I get it going well with my white blonde tele (bigsby) and the white blonde cab, it will be a killer looking rig as well! In any event, it sounds good through both cabs.

For $200 it seems to have been a pretty good deal.
