The 12AU7 to 7193 adapter arrived today. The quality and workmanship is actually very good.   It did not work in the Sunrise 2; quiet just like the Ember--6 or 12 volt setting. The heater filaments both glowed though.   I whipped out the DVM and went to town. What I found is that pins 5 and...

It sounds like the two connectors on the top may be reversed. Turn off the amp and reverse them.

Hello,   I am waiting on the 7193 to 12AX7 from eBay also. Did it fit in the amp OK?   Have you tried removing the FE and putting in a known good tube?

And you can actually hear all of those factors with multiple instruments playing and differentiate between them?

You use a lot of descriptive words here: attack, decay, sustain, release, synergy, extraction, organic, etc. I doubt that you are that well trained and know what the words actually mean. Are you just repeating words you read?   In agreement with those that state adding more circuitry to the...

I started with a Bravo amp and while they do sound "good", they are basically disposable. The worst part is the printed circuit board (PCB). They are cheap for a reason, try and get your $$ back.   Garage1217.com makes amps with the similar architecture as the Bravo, but with high quality...

This thread is a tragic waste of electrons and pixels....................

I am a hybrid loon also. I have a Project Ember which can drive 32 to 600 ohms with authority. That is the beauty of hybrids. I use an ART EQ355 31 band hardware EQ. Good reviews.   FWIW: For those who might want to try EQ without spending any $$$, FooBar 2000 comes with a 21 band digital...

Hi!   Yes. The aluminum plate has the larger tube hole to accommodate the adapter.   Isn't tube rolling grand?

Great to be back! You can order the Ember and the RCA gray tube at the same time. Be sure to order the correct chassis plate. You will save a lot of $$$ in tube rolling by starting at the top, however the rolling experience is worth the $$$.   By starting with the 6SN7, you will have a great...

Here is my four cents (adjusted for inflation):   I use a 31 band hardware EQ. Foobar 2000 (don't know if there is more version) comes with a 21 band embedded and you can download a 31 band version. My ears cannot hear any ringing between the two and my 10 MHZ scope does not display any that I...

Hello Ember Rollers,   I'm back in circulation--I included a pic of my tube rolling rig. The 6SN7 stays in the EMBER--it does sound a little better--possibly due to the 48 volt power supply. It gets more play time than the Sunrise due to the 6SN7 which is the best tube I own.   The Sunrise...
