Groove Tubes ECC83S

ECC83S Preamp Tube

The ECC-83S/7025 is a classic euro type tube with a very flat frequency response. Its basic character is very clean with a very good bass response. This tube is the conventional standard tube that has been used in many British amplifiers for a long time. In the first gain stage this tube can change the basic character of the amplifier significantly, making the amp cleaner and more dynamic. In addition, the ECC-83S/7025 is ideal for bass amps, and especially for the typical hybrid amplifiers.

  • Medium gain tube
  • Pronounced bass
  • Harmonic distortion

medium gain, full sound- good for class A practice amps
21.05.2016
This is an excellent tube. I bought it as a replacement for the stock tube on a VHT Special 6 and the improvement was huge! I didn't want to make the amp dirtier or cleaner, just the sound to be bigger, fuller and the amp to retain the blackface-type cleans.

The description is right. It's a medium gain tube, the amp has a nice response across the volume pot, as it starts to overdrive just after 1 o clock. The bass is also very nice, a bit too pronounced for this amp, but in a live situation it really shines. The amp doesn't get lost in the mix, although is a small, low watt design.There are no rattles or other noises

I have changed 3 power tubes on this amp and the differences are marginal compare to the swap of the pre-amp tube (maybe the stock tube was really really bad)

This tube is highly recommended for a practice amp with only one pre-amp tube, it really gives life to the sound. Usually these amps have small speakers and lack bass (not the VHT though), so maybe this is a suitable solution.

The 12AX7 alternative
Steeve_Julius, 14.02.2019
I really prefer the tone of the ECC83 instead of the regular 12AX7 4 preamp applications ...much more balanced in the low mids N less harshness in the higher frequency range... GT tubes is among the best brands IMO 4 a killer preamp tube choice
