I'm in the "It's old, recap it!" camp regarding the 457 and it's electrolytics. Others may disagree. I do recommend replacing C179 (2.2 microfarad tantalum) with either an electrolytic or a higher voltage tantalum. But that's just because I had one explode when I had a radio keyed up.
Now I'll shut up and let the people who actually know something chime in.
That's usually a good place to start. Good luck, I hope you bring her back to full health.
We all fat finger occasionally so no worries. Sometimes the results are just a little funnier. Thanks for the laugh!!!
Nice work . Im getting ready to do the same on my old TRC 457 .... Can you give any tips ...
Hi in the. Power supply I used 4300 uf cap I tried to use audio quality caps nichicon gold in the audio section.. C 179 is ais a tantalum 2.2uf 16 v replace it with a 25 or 50v 2.2uf tantalum or electrolytic in the back. Of the radio by vr7 there a resistor in place of D23.. place it with a diode.. In34a or nte 109 or nte 110 to open up the audio without disabling the cliffing circuit... Check R161 56 ohm 1 watt if itooks like it headed up replace with a 2 or 3 watt carbon risistor 56 ohm 1 %
