yeah me too.  I have a dynalo I need to  recase and it just needs a reg like this

I can answer #2 because I recently had a bad experience with it.   During power up, the output capacitor is not charged, and during the 30 seconds or so before it stabilizes, there is DC in the output approx. 60 volts.  This is bad.  If you have headphones connected, they might not...

any updates?

Nice build.  But smoke is not good. You should power off and check.   I hope you got the orientation of your mosfets right, because you mounted them at the bottom, then you should have mounted them facing the other way.  

Here is amb's informative post on this subject that I found recently:   http://gilmore2.chem.northwestern.edu/ubb/showpost.php?fnum=3&tid=7352&pid=68051&fpage=1    

Nice, clean look. 

Cool.  Looking forward to your vid.   I got a pair recently for cheap at newegg ($13).  Sound is ok but muddy is the right word.    What the "blu tac mod"?   I also read somewhere about drilling holes to improve the bass.       

I came across some of my notes on this chip.  Seems that a pulse rotary switch Alpha SR10030 can be used instead of push buttons.  I have not tested this yet, but its available at Mouser .   http://www.mouser.com/catalog/specsheets/TW-700001.pdf   pricey at $6.40 though...   Any...

Grounding the inputs means shorting the ground lug to the signal lug in the RCA jack.  Its like the minimum position of the volume pot, where essentially the wiper of the pot is shorted to ground.  But because of production tolerances, its only "almost" shorted, not completely shorted, so there...

Are you sure you're not hearing the hiss from your source?   Ground you inputs.  If you still hear hiss its from the amp.

  See here: http://web.archive.org/web/20060717211152/http://www.pedjarogic.com/spot/index.html I was planning to do this a long time ago, but somehow it fell of the radar. I still have my chips though. Play with it and let us know!

very nice first built LeMat!

Not married and no kids?   GO FOR IT !!!

Thanks.  I enjoyed planning it.  Not so much drilling, though.  Those holes are a pain to line up.   The aluminum  covers  I found in my local electronics shop.  Those are actually aluminum spacers from a hard drive -- I would guess from the platters. Quote:  

Yup, its ebay. from seller hlly_audio.

Here is my first tube head amp -- The Bijou.         No tweaks yet, just the regal mod.  Sounds really good as it is.    Thanks to runeight for an excellent project!  

Finally done!!!     More pics at the post pics of your build thread.

I saw the schematic using the link title that Kevin did:    http://gilmore.chem.northwestern.edu/ionovac2.gif       Quote:

You should replace it.  It might blow, just like it did in my build -- see post 3718.

caps underneath is how its usually done.   Quote:

Whats the best way to fix pots that still leak signals at the minimum position?
