Yes, but storing the doner devices, occupies our storage space and that is a menace for people like me, who operate from home! I get such donor device boards as and when required, instead of storing them, though I do have some collected. Many thanks for your comments, dear Yogesh Bai!

I understand how you feel Parasuraman. I wish there where more forums like this one. It would be nice to meet like-minded that share the same passion for restoring these old sets.

It shows only 8 pins and not 9 pins as mentioned by you. I think pins 2 & 10 are not used. Even in page 42 of what you sent, BA524 does not show pins 2 and 10. Many thanks for your expert comments, dear Albert!

Never heard of carbon resistor printing on the board before.
Now a days Most of Repairs depends on Donner Devices, because you can't get reliable material in the market or unavailability of materials.

But here in the compendium collection book you will find your exact BA524 amplifier!

Restoration of such antique sets is always a thrill! Many thanks for your comments, dear Mark!

How I wish like-minded people like us could meet in one place for a get together! Unfortunately, I am now not in a position to undertake any travel mainly because of my wife's condition and secondly the financial burden due to soring medical expenses has curtailed any extravaganza!
