Larry/Star Grounding for Metro 100w Kit

Post by LJay942 » Mon Jun 21, 2010 4:34 pm

Hi everyone :)

I'm about to embark on the MetroAmp 100w Plexi Kit. I'm piecing everything together and I'm curious as to whether or not there is a Larry/Star grounding diagram for this kit as well. I used Larry's Grounding/Star Grounding on my JTM45 and really liked the way it worked out.

Just wanted to introduce myself to this section as well!

Thanks!

I'll use that, I usually opt for the star grounding because I hate soldering on the back of the pots.

I had a question about this and I figure this is as good a place as any to post it...

The HT fuse Center tap originally connects with the OT center tap and Choke at the spare board turret. When you reroute the HT fuse center tap to the ground at position 5 with with the main caps and rectifier diodes, do you also place the OT center tap and choke at this location?

Essentially I'm saying is it HT Fuse Center, OT Center Tap, Choke, Mains, and Rect. Diodes on ground 5? Or just diodes, Ht fuse Center, and Mains?

If the OT Center tap and choke don't go on ground 5, do they just connect together like normal?

Any info would be greatly appreciated, as I didn't see this discussed on any other grounding posts.

J-Sty, lemme look at the one minute and get back to you on this. I'm still very slow when it comes to reeling this stuff off. It took me quite a few 'minutes' just to get it together in the first place! And I've been busy playing since! :lol:

Well I don't think I do... I just wanted to make sure that since the HT Fuse Center Tap was connected to them originally, it still doesn't have to when I connect it to ground 5. So, Assuming I don't ground the choke and OT Center tap, to I just connect them to each other as per the original 100 watt layout?
