Designed with the breakthrough Odyssey Circuit
The new Black Ice Audio F35 is a state-of-the-art stereo tube integrated amplifier sporting a new breakthrough circuit design by Jim Fosgate - that includes touch sensors, LEDs, and a look that wants attention.
The dual chassis design is laced with carbon fiber and mirror-finished glass panels decked out with LED back lit touch sensors, that provide a rigid home for the one of the newest circuits to date.
The Odyssey Circuit, designed in 2015, is a dual phase V drive circuit. With El34 power tubes, it pumps out 60 watts of pure tube magic. Silky smooth and emotional, the days of the smoke filled, low light jazz clubs are making a come back.
Using the Exact Biasing Vu meter, changing over to the 6550/KT88 power tubes is a breeze and the F35 becomes 70 watts of dynamic force to rock any room.
When it’s time for the neighbours and the kids to go to bed, the fun doesn’t stop. Plug in your headphones and press the headphone button to move your music from your room to your own personal space.

SIGNATURE SOUNDThe signature sound of the F 35 is a fine line of transparency and musicality that results in an accurate, yet organic & natural washing-over affect.
Because of this wonderful mix, choosing the right tube will have a major impact on the overall sound of the amplifier.
Unlike other manufacturers where the circuits in their equipment require you to use a certain type of tube and brand with their products, the Black Ice Audio amplifiers make it easy for you to roll different types and brands.
With the use of the on-board meter and the tuning wand provided with the product, you’re able to bias accordingly. It’s that easy.
PREAMP TUBESThe stock preamp tubes you can choose from are the 12ax7 by Tung Sol or the 12ax7 by Svetlana.
The Tung Sol 12ax7 is a very clear sounding tube with crisp sparkling highs, focused mid range and a tight base. Where the Svetlana 12ax7 will give you smoother highs, a warmer, fuller mid range and a textured bass. Both tubes give a very three-dimensional holographic soundstage.
POWER TUBESThe stock power tubes are Electro Harmonics EL-34 and the Tung Sol 6550.
The EL-34 will provide the listener with a sound that is best used for simplistic music like jazz and vocals. The result is sweeter highs, fuller and warmer mid range that show off the nuances in the music. Best for vocals and a punchy base that will drop off at 28 Hertz.
The Tung Sol 6550 ss for dynamic music like rock, hip-hop and big classical. The sound will have neutral highs and mid range with stronger better bass. The bass will roll off between 22 and 23 Hz providing more slam and dynamics.
TUBE ROLLINGIn regards to tube rolling, the owner of the F 35 can enjoy exploring and doing a little research. This includes learning that tubes from different regions of the world produce different types of sounds in the amplifier.
For example; Tubes from Russia will have a very clear defined type of sound Extended highs, focus mid range, and a tight bass. Where as tubes from America are going to have smoother highs, fuller mid range and more of a boom boom in the bottom end. You will find tubes from Germany are articulated compared to the tubes from China were the highs are rolled off with a very lush mid range and a bit of a sloppy bass.
Knowing where tubes come from will help you decide which sound is right pair for you and your system.
Circuit board layout
Only two circuit boards: Control board Signal/power supply board - integrated to lower labor cost to continue offering price to performance for the customer. One reason we are able to offer the prices we do. (Less connections for less chances of failure).
Tube biasingWe know how difficult and time consuming biasing tubes can be. So we incorporated Exact Biasing to the design to make it as easy as possible. The centralized back lit Vu Meter and the Biasing selector switch make checking the bias amperage in real time simple with a turn off the knob. Using the provided tuning wand and the back lit Vu Meter each tube can be biased exactly where you want it.
Touch sensorsWe wanted to incorporate led back lit touch sensors to the design to make the front panel as sleek and smooth as possible and to have that seamless mirror finish. Having touch sensors the user interface is as modern as the current cell phones and appliances on the market today. We use the most up to date capacitance sensors to handle the extreme temperatures that tube amps generate yet allowing the user to use the slightest touch to command.
ChassisThe Dual chassis is an unique design. Each chassis is 3mm thick Stable and sturdy construction Aluminum backed glass on transformer cover. Face plate is steel backed glass.

Musings from an F35 owner
SHUT UP...SIT DOWN...and LISTEN!
I’ve been ready for a full tube amp for sometime but I’ve been reluctant to again spend mega bucks to obtain a tube amp that can drive my fussy Maggie speakers.
Already a Jolida fan, I thought I’d take a chance on a new Black Ice Audio F35 rather than buy used (a gamble at best).
After a brief warmup and gaze at the exposed fire bottles (this amp is beautiful), I was blown away!
I generally ignore the “reviewer” superlatives, but in this case, they all apply! I could probably add more. Let’s just say, this is an absolute gem of an amp! It drives my system with ease. It’s everything I’d want in a high end tube amp without having to take out a second mortgage!
It’s incredibly accurate and feeds the soundstage monster within me.
Massive transformers....a real metal remote control, and (in my case) a gorgeous black gloss finish begs this 50 lbs plus gear to be displayed! It even looks cool when in standby.
Get one of these! Put the thousands you will save towards the college fund or a down payment on that new car... you won’t need to spend more to satisfy your love of music!

Waited too long to switch...
Can't enjoy solid state anymore!
The difference between solid state and tubes is a beautiful woman blowing you a kiss - and an even more beautiful woman locking lips with you. One is just so much more intimate, involved, thrilling and lasting.
I have the F35 and F360 feeding PSB Imagine T3's. Jerred (owner) did the 1st upgrade package on it for me with naked Z's and I'd highly recommend it.
It's oozing midrange so thick and sweet - with a completely open, crisp and fresh airy sound... it's the best of both worlds. The bass acts like I somehow added a subwoofer - deep, controlled but also more delineated.
The sound is infectious. Even my wife is hang'n around longer to listen - for hours. Crazy!
