Sovtek EL84

Bought these to replace the stock ones in my Laney Cub 12R, which were making loud 'popping' noises.

No issues with these in the four or so years since doing that.

I also couldn't hear a difference between before and after (except the absence of the popping noises!) - at least on the Laney it seems not to affect the tone too much.

I'd definitely recommend these, even just to keep as spares, especially because getting these ones from Thomann is significantly cheaper than anywhere else, at least in small quantities.

Sovtek is probably the only brand where you know that tubes you order and what you'll get. Fender uses them, I use them. THey are durable, low noise and sound great!

Bought to replace a bust tube in my Vox AC4 - does the job and is very well priced. Well done Thomann.

Very good for the price.
Used them for a whille and they never failed me

well, not cool but hot!
Have them on a 18watt clone for 3 hours 1 to 2 times a week for 6 months and they sound just as good or even bether than whey they were new.

I am pretty sure that this is KGB's secret ammunition that was designed for low watt tube amps. You plug these guys on to your amp and your amp starts to work like a heavy horse with a breath of fresh air. Luckily this is not a secret anymore :)

I use these tubes in a Bugera V5. They do their job well, but look like they are poorly assembled. No complaints about the performance tho, they last a long time
