GM70 Tube Amplifier

Here it is! Fabulous, musical, powerful, heavy weight tube amplifier – GOLEM  GM70. 

This super engine I finished two years ago. Detailed wiring diagram is confidential. However I can write some specifications:

• GM70 tubes

• ECC88 and 6N6P tubes for signal input/driver section 

• Small tubes powered with tube PSU using Ogonowski superb chokes

• GM70 anodes works on 900 V rectified with 5C8S rectifier tubes with dedicated heater transformers

• Single ended triode operation

• Pure class A

• Zero feedback

• Power 22 WPC

• Ogonowski filtering chokes 

• Ogonowski output transformers, impedance 8 Ohms

• TAIV VC03 R2R volume controller with input selector (4 analog inputs in total)

• Chassis completely designed by me, also work with application of heat resistant paint 🙂

• 50 kg net weight 🙂

Now I use it as my reference amplifier. I do not need no other amplifier during rest of my life. It sounds so good.
