The Blackheart BH1H

We can modify your own Blackheart BH1 or supply ready modified amps to order.

The Blackheart BH1 is an interesting valve amplifier which uses an ECC83 valve as an output valve as well as a pre-am valve. 1 Watt, Class A Single-Ended Volume Control DC Power to filaments for super quiet operation 4, 8 and 16ohm speaker outlets

1. It’s a great little amp and great value for moneyand at 1 watt you'd think it would be quiet enough to crank the volume up to '10' without annoying the neighbours but, in fact, it's pretty loud. In a medium size room, which is where most people have to practice, a 1 watt valve amp can be so loud that you would have to shout really loud to be heard (about 100 decibels) - and around 1/10th of a watt is what is often referred to as “bedroom level” for late night noodling.
2. By adding a Master Volume control and Power-Scaling™
   (see http://www.londonpower.com/pscaling.htm) you can achieve any level and combination of pre-amp and output stage distortion down to less than 1/10th watt.
3. The result makes this little amp sound even more amazing and gives a wide range of tonal options
4. I have also found that the examples I have seen have poor quality Chinese valves.  I am surprised that this is never mentioned elsewhere so maybe some examples have better valves.
