Noise was spectacularly low, the noise floor being below 0.1mV RMS. This translates into over 100db Signal to noise ratio for full power. When related to an output voltage of 2.83V (equivalent to 1W RMS into 8 Ohm) the signal to noise ratio is still 89db! This is the quietest 300B SE Amplifier I have ever measured, including my own designs. +

"ECC81 is a medium gain (μ approx 60) has an anode impedance of 10,000 Ω" "ECC82 is a low gain (μ approx 17) 7,700 Ω" "ECC83 is a high gain (μ approx 100) and has an anode impedance of 62,000 Ω." There are some big differences across the 3. Get some ECC81's. they seem readily available at descent prices even for NOS valves.
A closer inspection reveals that the new tube’s inner construction more closely resembles their ECC81 (12AT7) but some of the materials are obviously different. It is indeed a totally new tube.
The 18watt site is run by unpaid, volunteer moderators, some of which have commercial interests in the guitar amplification business. They will all attempt to the best of their abilities to not interfere with commercial discussions.

Euterpe is a single-ended headphone amplifier with unbalanced circuit design, so there are no balanced inputs or outputs. The lineup of tubes is classic Auris, with the use of two 7-pin Ei PL95 tubes, which are the equivalent to 6DL5, and a single ECC81 input tube, also known like 12AT7 (running in Ultra-Linear mode).

The block diagram of the Philips TX1410U. Apart from the introduction of the ECC81 dual-triode in the tuner module, the valves were identical to those of the TX400/500. The only exception is the EB41 dual diode, where for unknown reasons the platform switched back from the newer and smaller EB91 to the EB41.

The presented thesis deals with a tube microphone using a condenser microphone capsule for sound capturing. Moreover, two essential aspects of a tube microphone – the basis of its operation and its design – are also discussed in this thesis. In the designed microphone, there is a vacuum tube known as ECC81.
The question is that the compressor uses a pair of EI 12BH7´s that I`d like to change to a matched pair of better tubes: Do you know what brand of 12BH7 tubes or substitute would be the best? I`m told that the ECC99 is a direct sub for the 12BH7, and also I remember someone telling that would be changed to a 12AU7/ECC81?

May 18, 2019 · Changing tubes in an amp can be a particularly challenging experience, especially since there seems to be such an abundance of them. For this article, we’ll concentrate on the question of the ECC83 vs 12Ax7 tubes. The truth is, there is no difference at all between them, and each one is interchangeable with the other. […]
