Xits X10 = liverpool half power?

[Taylor2011]

It could just be my eyes but I think they are 30uf filter caps in the power supply not 16uf? And there are 5 of them, not 6. Please forgive me if I missed something in the discussion about this.

You're right. But the cap are 6 as per the pictures.

Check the latest schematic (p.13) and Version 2 close up photos again. They are Mallory CDE TC74 16uF caps throughout. XITS is not using the 30uF Sprague Atoms any more.

Hi Paolo,

If you have a look at the guts picture in the second post on this page of the thread you'll see there are 5 caps:

It looks like this thread contains photo's of different amps, or is that a black cap near to the power switch?

Best wishes,

Chris

Hi Colossal,

Sorry for the mix up, I was just going by what I saw in the original photos.

Great work on the schematic by the way.

Best wishes,

Layout Finished? Any comments are appreciated. Couple things:

1) grounded V1 and input togther at first filter cap/star
2) V2 cathode and tone stack grounded together at second filter cap
3) PI grounded at third filter cap (will prob move the PI tube over a bit)
4) grounded Ptubes at their filter cap
5) rectifier area not totally decided on whether to do the original or latest version and I might move it on top of the G10.

edit layout removed adn updated in a post reply to this one

That is a good looking layout your tempting me with this build

Mark thanks. Seems to be coming together albeit slowly... would love the have to company since it seems I'm going it alone right now.

Cmon Mark, nail this puppy.

I'm not knowledgeable enough to help you build it, but I can help you flog it once it's built!

i'm making a 30w prototype right now.
so you're not alone.
Once I'll understand how this amplifiers works and can be tweaked, I'll make the definitive version. Also becasuse I plan to make a great transformer "swap battle", so to get the right one.
BTW nice idea the use of the solen caps. I already have used them in another fender style amp and they make a difference IMHO.

Nice! Keep us posted on those few values we were missing.

What PT and OT values are you using? I am doing a 300-0-300 and a 25W 8k. I am debating the terminal strips for the Ptubes and i'd like to know how the heater buss bars work for you as well...

For my choke its 440R and might throw a resistor in between c1 and c2 to compensate considering the 1k that used to be on the older version

V,
I'm down my man. I'll start ordering parts tongiht. I think we are almost there. Lets tackle this sucker.

[surfsup]

T, I emailed you all my stuff. I hope you can get through all that and actually order. I already had an LED indicator, some switches, etc. Keep in mind I got the big solens and my layout is for that with a 2 1/2 inch deep chassis (18x8x2.5). If you move forward, I can email you the drill plans or edit them to change the size of the caps and locations to drill the turret holes in the G10.

I also ordered a few different types/brands of caps/resistors (carbon film and PRPs and ploystyrene/polypropylene) since I don't know what the solen fast caps are going to do.

Oh and I went with the 1M dual gang MV.

Raven, when I'm done we can hook up for sure. I checked out your site, are you the Dr. Scientist? Nice work...

[surfsup]

Okay I updated the layout a bit to add a VVR3 and moved the PI over a bit to give more room for the OT secondaries and 4-8-16R speaker jacks. About the only thing I think I might do is:

1) put the rectifier stuff on the main G10
2) maybe move the pots a little closer to the input to shorten the runs

Let me know what you think. I think she's nearly done...
