In the end, a simple lower power amp like the Akitika might be educational, but is no substitute for years of experience IMO. Should mention that in all cases my DIY goal has always been to have a useful product in the end. …
The power amplifier stage is required to be a Class AB amplifier with between 3W and 25W of output power and a THD < 1%. While breadboarding I had issues with thermal runaway and asked the professor for suggestions.
After seeing a few posts asking about DIY amplifier stuff I decided to start a thread about an amplifier I'm making. Pretty straight forward and the simplest practical DIY amplifier I have come across, using borderline ancient AD-161/162 pair germanium transistors. Output power is about 10w into 4ohms (real watts RMS) Main reason I decided to build this amplifier …
The simple truth is that a very simple DIY tube guitar amp will generally sound much better than even a much more complicated analogue DIY SS guitar amp. Throw together a couple of 12AX7s and a 6V6, and, if you have a good pair of ears, it will sound much better than Rod Elliott's quad-opamp, 14-discrete-transistor, juggernaut.
Based on this amplifier, I decided to make a amplifier working in Class B. The resulting schematic is as follows: Resistor R10 sets the idle current at 200mA. Using the …

The amp has a Cntrl-IN switch so the amp is on when the switch is on AND when 12v is applied to the input from the pre-amp. With this switch ENABLED, the bulb glowed for a few seconds, then turned off. HOWEVER, when I defeated this switch, so the amp is on when the switch is on, the bulb stayed lit. The power on LED on the amp was glowing.
Some 6BQ7's can be rather microphonic in a guitar amp but some are OK. 4 stages is not excessive gain either. There is a $100 guitar amp design challenge on this forum. One of my designs started out as a "18 watt Lite" with 6BQ7's and 6CW5's. it now uses a series string heater circuit to fit in the $100 budget.
This project came about after happening across a prototype VHT all tube bass amp. I posted a thread on it. Long story short, sounded fantastic, but just wasn't powerful enough for my needs. I set out to try and capture it's sound and make it louder. The original amp was definitely a test mule as it was very much modified from the original layout.
One easy way to reduce B+ is to set up a buck transformer using a 2 amp 12.7v center tapped radio shack transformer. This lowers the 120 on the primary side to 106-114ish …
