JJ Electronics 12BH7-A Vacuum Tube

The 12BH7-A is great for low-output applications that require a relatively low plate impedance over other small format tubes.  If you think in terms of gain (mu), the 12BH7-A would be similar to the 12AU7.  Consider pairing this tube with our MOJO1580 output transformer to create a low-powered "bedroom level" output section during your next build.
