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...

I have done the LD3 and Ember side by side and sold the LD3 later as it got little play time. The LD3 is a terrific amp in its own right. It has a warm, rich sound.   The reasons the Ember stayed:   Much more power Can play phones from 32 ohm to 600 with authority. LD3 cannot go below 300...

Hello Ember mates,   This is my first time on this thread. I've attached a pic of my rig, which I nicknamed VaderNator in honor of Star wars 7. The metal chassis and tube DO give it a new look.   I just happen to have the 6DJ8, 12BH7 and 6SN7 mentioned above and I agree wholeheartedly. I...

Hello gentlemen,   You can get the OPA637, which is optimized and more stable at Mouser Electronics for about $25. They only come in a single channel so you would need two.   I use them in a custom SS amp I built--they are considered the best for a reason.

Yes, I do know. I am saying that I was  playing the 6N6P before the SC was conceived.

An interesting thing about the 6N(or H)P. It is also used as the power tube in the Little Dot MKIII, which I also have. It can't be used in a stock Ember--too much heater current draw, about 800 ma.   I run one in my PS2 until I upgrade my Ember. I find the sound to be similar to a 5751, very...

I have an Amperex 6201 PQ (Premium Quality) which is an "industrialized" 12AT7 with gold pins. At first it seemed kind of dark but with time it has "blossomed" to a very musical sound. It is also rated at 10,000 hours use.

I have both PS2 and Ember. The main difference I see is that the PS2 cannot drive higher impedance phones and the Ember can drive just about ANY dynamic phones. It can drive my 600 ohm Beyer DT880 and AKG Sextett with power to spare. AKG K702 is considered difficult to drive--Ember really brings...

Hello all,   I'll chime in on the 5751. I like them enough to have five. I play them in my Ember and PS2. To me, they have a solid state like sound but still tubey!

I posted what is below in Project Ember Review by mistake:   To digress a bit to 6 volt land: GE 6DJ8 smoked glass vs Sylvania 6922 vs Voshkod Rocket 6H23.   The 6922 (Google research) is considered an upgraded 6DJ8 The GE 6DJ8 has a "smoked" glass, which is actually an RF shield--it IS...
