I need to replace my two 12B4A tubes. Can I use 12B4 (minus A) tubes instead? Is there a difference? tks
Very proud new MAD owner here. Running JRMC > DACport LX > MAD for my buttoned RS1s! What a sound!
I've got a Raytheon 5751 windmill in front and some sort of Raytheons in back.
My question for you guys is: Will rolling some NOS GE's in the power position change SQ at all? Or is that negligible at best? Also, I don't really care to have 10 audio tubes on hand, but maybe buying one or two more would be nice. Suggestions for those that won't set me back more than $50 a pop?
I know, right.
What a nice combo....congrats.
No, no need to mess with the two back tubes....best tube I found for the RS1i combo was the Sylvania 5751 triple mica black plate..
Enjoy your music.
I see the dampers on your tubes, are your tubes microphonic ?

I have not noticed any microphonics. Honestly I've owned those dampers for about a year but I was using an amp that had tubes that were just a hair too small for them. Just trying to make them feel loved
Any one here uses the 2 sets of inputs on their HD Ear+?
When I plug in a second rca source, the sound of the first source is affected.... adding noise to high frequencies... even if the 2nd source, a dac, is turned off.

It is normal, the 2 inputs on the back of the MAD EAR+ HD are designed to be in loop, which means the signal from one input is passed on to the other input jack and let you connect to a separated preamp (unaltered, no volume control by headphone amp)
The output jack are used for passive preamp funcion which let you connect to a power amp and use your MAD EAR+ HD as volume control
Read the manual and you will understand how to operate your amp: https://hollowstate.netfirms.com/manuals/Eplus%20HD%20users%20manual.pdf
Connections are all explained on page 3
Yes, Lloyd is a great gentleman....and a wonderful amp builder.
