Stereomour II / Re: Stereomour complete - Where's the bass?

« Last post by blue360cuda on June 28, 2025, 05:22:56 PM »

Great job on finishing your Stereomour II build! For the thin bass, try switching to the 4-ohm taps instead of the 8-ohm ones, as it could help with bass extension. The Mundorf cap you swapped might also be affecting the low end, so testing the stock cap could be worth it. Additionally, give everything some time to break in, and maybe try different sources. Keep tweaking, and it should improve!

Thanks for the idea!   Since I got all the factory upgrades installed my plan was to remove the trim pots behind each 2A3 and install a pair of DPDT switches to be able to switch between impedances. Originally was planning to do just 8 and 16ohm as I have 8 and 16Ohm loudspeakers but might go all out and do the 2-4-8-16 switch option just out of curiosity if anything.

Circling back around about the bass - wow , I totally eat crow on that one!  The Stereomour II is seriously my favorite amp!  I did settle on the Mdorf silver/oil for the 4.7uf and 0.1uf caps and honestly they do sound great. Now that everything has a broken in a bit it's lovely.  The only other "upgrades" were some NOS military grey plate RCA input tubes and NOS Guiguang 2A3s I found on AliExpress, which surprised me how great they sounded. The bass isn't that kick you in the chest boom boom solid state stuff - but its very solid , tight and musical. I'm loving it!

If you don't really have access to a place to try things, then your best bet is going to be to buy used pairs on eBay to try out, then just resell them if you don't like them.  You'll lose a few bucks here and there on shipping and auction fees, but that's going to provide you with the most opportunities to try stuff out.

Yes, your line voltage is a tad high, but that's acceptable.

BeePre / Re: Need Help - High DC Voltage at Terminal 25 & 6

Don't feel too badly about it, when we wrote the original manual for the BeePre 1, I managed to get the 4 pin socket numbering wrong somehow.  That wasn't particularly fun to fix!

Moreplay / Slightly High Raw B+

« Last post by ambd1 on June 28, 2025, 12:35:33 PM »

Hi All,

I´m a newbie for amplifier kits. I have soldered cables and transformer terminals in the past, so I´m improving my soldering skills, but this is my real first build.

I am going slow and it is all going well. I just performed the Raw B+ test. My incoming AC voltage is 124-125 volts. On my B+ test I get 326-327 volts DC.

I have checked all the resistors and capacitors and it all looks OK.

Is that Raw B+ OK?

Thanks,

Alan

Ok, I finally have the wife's permission on picking up a set of head phones.   I thought choosing my speakers was a pain, this is worse.   I am not looking for electrostatics but a quality set.    Something like the Sennheiser SD800's or similar to give you an idea.   I will be building the Mainline 1.1 from what I have read.   I like the thought of planers but I live in BF nowhere and have no real ability to try to an thing..   My closest serious store is about 3.5 hours away in the Kansas City area or in Tulsa.  So with that said, are there any directions you can all steer me.   For reference, I have both Eros 1 and 2 phono preamps,  Beepre (1), Carver Black Magic 350's mono blocks and a Vincent 332 amplifier, two turn tables, VPI Classic 2 and Micro Seiki DD8, Magnepan 3.7I's  speakers and various other toys, cable, etc.   Thanks in advance

You guys have been the best.   I retired 6 years ago and never looked back.   Well not exactly, I never stop looking back to my friends.

Definitely committed to getting both out as soon as we can. PB, PJ, Dan, and I have been actively discussing often and they have an open offer for me to come out and shoot the manual as soon as practical.

SEX 3 is my favorite amp and I can’t wait for people to see its successor.
