Check the output transformer wires where they go through the chassis. Hole is small for the wires. Mine had a nick in the wire insulation.

Isn't the 80 suppose to be at the 6:00 with the 40 at 9:00 after the rectifier?

This help

Guess when you have the time, pull the bottom and see if anything looks bad/burnt. I'd look at the parts on the board good.

This is the one I've had my eye on for a while now. https://www.primaluna-usa.com/prologue-three Is it the same? The ProLogue Three is true dual mono with TWO toroidal power transformers, choke-regulation, point to point wiring. Only thing I see in common is the output board?

What would something that is a true dual mono have in common that both channels would go out?

looks like the last ones I bought were Inside Dia.: 0.173" Outside Dia.: 0.205" Shoulder Dia.: 0.344" Fits Bolt Sizes: #8

Real life got in the way for a bit. Seems like I may have some time, back to this. Sold things to make other things happen. Couple transformers changed. Have to figure out the power supply with items I have. Trying to figure out PSU Designer. Could someone tell me if this will work? Looks...

Probably picked a bad time to start this. Between Vacation, long weekends, and the rain it's been hard to get to this. I've managed to get the holes drilled and started mounting parts. Next to start wiring it.

I like the DACT type https://www.ebay.com/itm/DACT-Type-21-Stepped-Attenuator-Volume-Control-Hi-Fi-Grade-D-shape-Shaft/201654839183

Nice

The one I did a couple years ago I used a ceramic 5 position selector, 100K volume and 250K Balance [never hooked up]. The dact type volume pots are nice.

Thanks for the suggestions and making me think a few things out. Really have my mind set to do the Kegger version at this thread http://www.audiokarma.org/forums/index.php?threads/kt88-ect-single-ended-amp-seul.382162/ One shot deal, Have to do the best I can this round because not sure when...

This is a build I've wanted to do, but never got the motivation or ability to do it. I can paint by number pretty good, but don't have much vision. So this is going to be a learning experience. Have been collecting parts for the day I was ready. Well the transformers came in and put them on...

Something like these? https://www.audioamp.eu/en-kategorie_593131-0-automatic-bias-control-system.html

Maybe get one of the upgrade kits like the ULTIMATE Combo upgrade kit from Tube Nirvana and build in chassis of your choice

Wouldn't the best place to start be by placing the main pot and the trimmer in their center position and starting over known good tubes? I have no experience with this and have so many questions, trying to see if I follow along. Original circuit had wire between the pins and and one resistor...

Can't see the front socket. Is there a place to measure the main bias pot then 2 others to balance the tubes? Looks like the 4 peach resistors are the ones you need to figure out

To move RCA look at the board. Will see 3 holes at the RCA jacks. Just put headers in there and use them to RCA jacks on case. I left the RCA jacks on the board. To put power and switch on the back just put IEC in, run one side to switch fuse and one leg of transformer, other side to leg of...

A couple sources will come up If you do a search on ebay for HN V2.6 Little Bear

2.6 is out. Comes with tube covers and what I think is an important feature. Switch to lift house ground

Have my arm board out right now Measures 119.75mm

I always tell them to have their pickup service to have cash when they come to get it. Usually the last I hear from them.

Says it's 3 watt Easy kit to assemble. Has diagram to populate the board. Wiring not hard to figure out. Just look at schematic for block working on and see where the wires go. Enough pictures out there if run into problems. I did enjoy building this.

Got it wired up. Playing music now. Still need to check voltages I guess. Sounding good.
