The B12a Quad is Black Lion Audio’s latest rendition of 312A-style gain with 70dB of bang! Housing four channels of Rock ‘n’ Roll punch in a 1U chassis, it delivers modern flair with solid vintage tone at an unbeatable price! Each channel of the B12a Quad has the same delicious Cinemag input transformer found in the venerable B12a Mk2, but also sports Cinemag output transformers, two front panel D.I.’s, output metering on every channel, and XLR/TRS parallel outputs in back! And if that doesn’t cook your noodle, the B12a Quad packs all of this punch at under $300/channel! – USA Cinemag transformers in and out – Made in the USA – Sounds better than anything else in its class – Better metering than anything else in its class Check it out at AES Booth #340 Attachments:

Curious how it holds up to the Warm. Swappable op-amps?

I gotta have my swappable op amps... Cinemag is a good feature

If they are like the original they have the 5 pin but how do you/we know they will be swap-able if we haven't seen the pcb or are we just assuming ?

It would be odd if a company that built itself on modding gear decided to not put swappable opamps in their own design...

I understand, I just didn't see any reference to the OA's being swappable, so wondered if that was confirmed or just hoped for?

The 500 series version is definitely not swappable. But my understanding is that it is discrete.

I am only aware of the warm tonebeast having swappable op amps nothing from bla ?

Understood: but that helps keep the common cold out of your mixes ?  |

But they wont have overheating problems like some DOAs, so they shouldn't need to be replaced/repaired. |

But how can you have an allegedly "API Derived" design without discrete opamps? Sounds bogus to me.
The question is not overheating. The question is audio quality and headroom. Discrete opamps generally operate at much higher rail voltages than chip, which translates directly to headroom and possibly s/n as well.
EDIT: As I understand it, most of those overheating problems were caused by the epoxy potting of the circuit board, preventing adequate radiation of heat.

So, guess you could mod in a little sister boards, just for op amps, with the female pin hole, like the tonebeast ,if you really wanted to ?

guess it depends on the price/value prop ? I would think the new BLA pre sounds like API, as it is supposed to, so swapping op amps isn't so critical ?

This one seams kind of point less unless you are like me and stubborn as hell and just want to mod it to say you did it. Yeah I’ll admit I’m stupid enough to have done that at times, but I think giving the man the finger on this one is kind of pointless. This is a price point piece and there are plenty of other 312 based pres out there to have fun with opamps! |
