Lilliput Valve Amplifier

Lilliput Valve Amp
The wood case is stick with an aluminum sheet as a purpose to ground some noise.
These are the choke and transformer for the amp. No matter how good my calculation, I still can’t make the transformer any smaller.
Have those hole drill and fit in all accessories, transformer, choke and sockets. Wood are easier to chip off, be care full when drilling.
Most of the time, I will fire up the main transformer to make sure the magnetic flux do not couple to the OPT.
Okay, rule number one, always put priority on your safety first. Let build up the power section first. HT at 220vdc.
This chassis is very compact. I almost use up all spaces.
The Lilliput circuit in this amp have very little changes, add in grid stopper, 100uf bypass cap for driver tube and adjusted cathode resistor to 980 ohm (depend on the 6as7 tube’s resistance).
With simplest circuit and components, this amp is awesome.
what amp is this? no description?
“I use Lilliput circuit for this amp with a very little changes”
Beside that, I use Russian 6N13S to replace 6080WC tube and 6N1P as to replace E88CC, else almost the same. So I still call it Lilliput Amp.
This circuit was designed by a German. Schematic at The Infamous tube Amp post.
It is ready to present lamps 6н13с
