Replace a 12at7 with a 12av7?
Should be fine but be aware the 12av7 is a hotter tube. It uses 150 mA more on the heater grid.  A pair of tubes isn’t a lot.  Gain is 41 vs 60 on the 12at7 so it may need a little extra power.  Your ears are the answer...if it sounds better to yo... 
The Raven Has Landed
My QSA Yellow fuse arrived yesterday, installed it onto my Raven Blackhawk and to my astonishment I now have a new Amp.  Insane a tiny fuse can make such an improvement…does not make logical sense and it hasn’t even been fully broken in yet.   A m... 
Quantum Science Audio Thread
My Yellow fuse arrived today and I have to say it blows the SR orange away in every aspect in my Raven Blackhawk amp. Just stunning a little fuse can make such an improvement.  Best $220 spent! I also bought a blue fuse for my DAC but it arrived w...

For the budget minded only…I tried these on a whim just to see if they were better than stock and at this price super low risk.  I was shocked with the results…they are still in my amp and Dac. At some point i will upgrade them like i did buying M...

Best Bang for your Buck DAC ?
I also highly recommend the Black Ice Audio FX Tube DAC.  On sale at times for $699 I was skeptical how good it could be atbthat price point but wow it sounds really good.  I liked the fact it used 2 12ax7’s and has built in wifi. Performs way abo... 
Raven Audio Nighthawk
Has anyone actually compared the Nighthawk vs the Blackhawk?  Is the Blackhawk really worth the extra $800 or just a minor improvement? Trying to decide ....Thanks 
Raven Audio Nighthawk MK3
@gregoriomth16.  I have Triton 2’s as well and am looking at the nighthawk as an upgrade.  If you don’t mind, let me know how the nighthawk pairs with the tritons or if I need to start speaker shopping... Cheers! 
Tube virgin looking for tube amp under $3k
Raven at your budget ....or for value a Black Ice audio  F22 at 1/2 your budget.  Throw in a fx glass tube wifi dac, some vintage 50’s-60’s tubes and you have a nice low maintenance initial set up that performs way above its price point.  https://...
