I purchased these to replace the EH 12AT7 tubes in my
Manley Mahis amps. After contacting tubemonger re suitable tubes they
suggested a Siemens and 2 Brimars one of which was this type.
The
sound of my amps changed quite dramatically. The harshness and coldness
in the mid was replaced by a much smoother and detailed sound, warmer
and more involving. Treble is smoother and not as upfront. Bass is deep
and more detailed somehow. Overall a great improvement.
The tubes sit on a black Plastic base and plug in as normal, this base is attached very well and no wobble has been noted.
I
tried a Brimar 6060 yellow T in this amp and preferred the cv 4033.
More life in the music, the 6060T sounded flat in comparison.
Overall a great upgrade to new tubes, not much cost and 10000 hr life. You can't lose.

The CV4033 tubes that I did buy will satisfy the 12AT7
tube rolling urge for a long time to come. These are in a totally
different league from the RFT and Electro Harmonix tubes tried
previously in Bottlehead Paramount amps. These tubes have warmth and
detail similar to what I experienced with Brimar 13D5 tubes used in a
Bottlehead Foreplay preamp.
