Amps

[LARRY L]

I just finished a Fender Champ kit from triodeelectronic, all went well, I made the chasses from .08 alum sign material, drilled the holes, scored the bends .02 deep with my wood blade on my radial arm saw, .005 deep cut at a time then bent with some force by hand, no brake needed, made some stencils for the black face, design a front ported cab for better a bottom...

But I keep blowing the 1 amp slow blow fuse when I turn off the stand by. The second fuse lasted for a while and the amp sounded great at all volumes, but when I turned it on again to try my Strat and then turned off the standby, a couple of seconds went by then pop the fuse blew. I checked the amp draw,- on Standby it's .22 amp, -Standby off it's 2.24 amps. (for about a second using a 1.5 amp fuse), then I turned it off not to blow another fuse. I am using a larger 15 watt OT. so to also use a 6L6 but I tested it with 2 diferent 6V6'S (JJ) in case the power tube was bad. The tech guy at trio has not got back with me after several days.

I just checked the speaker and it is about 7 ohms.

This is odd, I cannot read any responses, after over 100+ views?? non listed??

If you had reponded, start a new thread with it, if you can read this.

You used a beefier OT for 6L6 so you should probably upgrade the power supply components. I doubt 1.5A would be sufficient of a fuse. Is the PS transformer capable of handling the excess current demand?

What spec are they? 

Did you trace all the connections based on your diagram in the kit?

Only other thing I noticed is it looks like (in the TE site pictorial aa764 diagram) there should be a direct connection to a filter cap section from the joined 1k and 10k resistors which also connect pin 4 of the output tube. 

Maybe post a larger and not as dark image.

I only tried a couple of 6v6 tubes. I'll get some more photos later today, I did check twice with highlighters all the wire pathes and connections according to the layout. It's on the triodeelectronics.com web site, under AA764 Champ black face kit. They said the 15 watt OT and a larger 10w 470 ohm resistor was all I needed to run a 6L6. The other tweed Champ kit's 5F1 layout calls for a 2 A fuse it has  the same 15w OT but a duel voltage PT. Thanks

OK here are more photos

Again if I am looking at the same pictorial, you should have a two connections from the joints (junction) of the 10k and 1k resistors. One lead goes to a cap section (triangle), the other ties to Pin 4 of the output tube socket.

From your pictures I only see ONE connection there. IDK 

[LARRY L]

I do have 2 connections, one is from the top of the turret and the other is from the bottom of the turret running up through the center and soldered at the top.

The pt is rated 650v ct @ 70ma dc

The tech guy at Triode said to try another rectifire tube, so I need to buy another.

[HKSblade2]

I couldn't realy see the second connection there. Everything else looked ok.

try a new rectifier tube, I'm just more concerned with the current. Still seems high. Did you measure that current in series on a DMM?

[LARRY L]

I measured from the plug, nothing fancy.  With the rect. & 6v6 tube removed, I got .12 amps.

The other connection you could not see is hidden since the line is connected to the bottom of the turret.

[LARRY L]

Well I found the problem, you can see it in the photo

the 2 watt resistor's turret is being grounded by the hold down screw. See the bottom left screw on the board. Now nothing works however.

[LARRY L]

I seem so obvious now, yet nobody else noticed it in over 500 views!

Good you found the problem. The pics don't really reveal the problem. Some may assume you are using insulated washers on the fastener. I couldn't really tell except for the one pic on the angle shot. Just like I was unable to see the details regarding the resistor connections where you said the one wire comes from beneath the turret board. Some posted DC voltage measurements would have helped isolate the problem as well.
