I know that this is an old query but 28 turns of wire around a 1 cm core of wood, aluminium, cord etc, but NOT iron or similar metal, to give a coil around 5.16cm long, will give you and inductor of around 6 micro-henrys. I hope this helps

Yes you can but you should observe the pin configuration each of them. TL071 is single drive, jrc 4558 is dual driver.

I was trying out your amp,I used BD 140/139 for Q1 and Q2,and tip 41/42 for Q4 and Q3,tlo72,-/+17.2vplus minus,(12v in series with 5.6v zener).PSU is -45 and +45 Everything else is the same.
At low volume below 20watts of power,sound is clean but as u increase there is very unpleasant distortion as if speakers are cut or damaged.
Speakers are fine,and play well on another amp.
Help me out here,what could cause such noise
Your fan.

I hope someone gets this and can help.
The transformer you say 8 amps at the top for stereo, but in the parts list you say 16 amp
Is this 8amp per winding, as most transformers are sold like this. Thanks
