My 1st amp just came to life......pics

[JandG]

I just fired up my 1st amp this mourning & after a mindless mistake of not hooking the center tap up on mains & easy fix. Music finally came from the JE Labs 45. I eliminated the lytics & I am using AC on heaters with almost no hum on my PIM-8L's. I set the hum pots close to center & have not even tried to adjust them, hum is almost non existant, very happy about that. I had some old Sylvania 45' & Tung-Sol 6SL7 WGT's & a nice 5Y3G in ST. I tapped signal after the 6SL7 for my bi-amped system. been 4hrs & nothing wierd yet. OT's are James 6123's & seem to be very nice. Nothing offensive as of yet. Not a powerhouse but great midrange & the fairlly high eff..Pim-8L's really like this amp. I am running the 16ohm taps at present, but I have access to the 4 & 8ohm taps also & will try them. Just pumped it didn't blow up.. I am using a 16 gauge power cord I had from work for speaker cable & cut it into 6' leghnths & terminated it. sounds fine.

Congratulations!

It's nice to find a couple of new amps being born everyday

This seems to be the Simple 45?

[JandG]

Yes, it is simple 45. I have not shut dang thing off since I inserted it in main system. 24hrs strong. I have been watching your 300B project with great intrest. I would recommend this JE Labs build to anyone. Mine is very quiet & has had to adjustments as of yet. Very smooth & not harsh. I even used mil spec stranded silver plated teflon wire that every one hates, but I have it in all signal paths & off all OT taps. Only heaters are 18ga solid from Ratshack.
I can not tell the cheaply bought mil spec wire from anything copper or solid silver I have used in mods, or preamps I have built.So I conclude that wire woes is mosty hokey pocky BS with heavy marketing driven greedy people praying on audiophile. The blue power cord left over from work that I cut up to 6' pairs & terminated sounds just fine. I have 1000.00 cable left over from stupider times & they collect dust because of bieng hard to use with my vintage amps & this old fashion terminal barrier gig. Chassis is solid wood with no plate & only a small 10ga ground bar for all grounds plucked from a section of 10/3 romex. I have had good luck with hard to use preamp tubes 26/27 with solid wood chassis & just small ground buss.This is the most enjoyable times in my audio & music fanatical life. Bieng able to be free of commercial offerings is oustanding to me. Hope your 300B project turns out great so we can all build a IT 300B. My 300B is PP & commecial unit. SS rectified & you can tell. Big bummer......It sits looking at me sadly.......*s*

Teflon insulated wires are great to solder! I use Audience hookup wires as they're teflon insulated and they're sold cheaply here in the Philippines by a dealer friend.

Thank you for the well wishes for my 300B

Dude,

SS rectification can work very well. As is always the case, implementation details matter. What sort of diodes are in that "box"? What does the PSU filter look like?

Congratulations! A very nice work.

It is with much admiration and a little pinch of jealousy ;-) that I congratulate you sincerely. I am seeking again and again for my first project to build. And I don't know wich one to choose. It always gives pleasure and hope to "numb-bie" like me, seeing somebody daring and succeeding.

Congratulations again
