Please see our article on 12AX7's. https://www.amplifiedparts.com/tech_corner/12ax7_comparison_of_current_made_tubes It will rate tubes by gain and noise.

Some people will match a preamp tube and this is what is typically referred to a "balanced." We do not offer this service. Most of the time is is unnecessary.

Hi, all 12Ax7's are comparable with each other. This will work just fine.

The Tung Sol is a very warm and creamy 12AX7 with nice detail. We would suspect that you would get these attributes with the Vox.

Both of these Tung Sol 12AX7's are ECC803S. They are very close but the gold pin will have slightly less gain in the mids. The ECC83 is a mid gain tube and will have less gain than a 12AX7 (ECC803S).

Absolutely. High gain preamp tubes combined with low numbered power tubes should provide your amp with earlier access to breakup.

The tung sol 12ax7 gold pin is an excellent 12ax7/803 preamp tube, low microphonics, nice midd gain, I have use the standard and gold pin.. I find the gold pin higher quality tube.. Use in my Bogner 101b and Fuchs custom Wildcard 100 D style amp in V1 for all channel. Highly recommend this tube.

This tube changed the sound of my amp !
That’s a positive change. I’ve searched for that elusive sound for 60 years, but when my friend Carl recommend your tubes, I’m so glad that my mind was open to guidance, because he was absolutely on the money. Thanks for a great product. Ray White

I replaced an ageing NOS in my Victoria deluxe. Very nice, sound - fluid and perfect for this amp.

I compared several 12AX7 tubes. The Tung Sol is pretty good. It's a little hotter and brighter than the Mullard CV4004 which was my favorite.

Tubes arrived quickly and at a good price. The tubes themselves are quiet and give my amp a very smooth sound and attack. I would purchase them again. They sound as good as some more expensive vintage tubes I've used.

Bought 3 to replace microphonic tubes in my Monoprice 15W amp. Sound great and absolutely no hint of microphonics.

I put this in V1 of my Blackstar HT Soloist 60. WOW noticed the 3-D sound they were talking about. Lot more headroom and bottom end on the clean channel, the OD had crunch to sweeping gain with a more pronounced EQ and presence response.Going to get a few more for my other amps.The Tung-sol sounded totally different in V1 then the OEM tubes.

I bought this to replace the stock tube in my behringer VT999. The pedal was useless to me and sounded like a bad fuzz pedal with the original tube. Then I installed the Tung-Sol and I must say the difference is huge. Now it sounds great with plenty of usable tones on tap and sounds more like an overdrive pedal should.
