Default Re: Restorers dream part 2 the chassis.

Cross dressing capacitors caused me a lot of 'fun' during my Eddystone 770R rebuild. I first assumed they were innocent resistors, but when I had problems with low IF gain I realised they were capacitors and nearly all leaky or open circuit. I'm not a fan of shotgun replacement, but in this case I had to.

However one big difference between restoring radios and TVs in the modern age is that a TV won't be used on air so doesn't need every dB of gain.

Because the Aurora has such a large output (6mV) it's a bit like living down the hill from Ally Pally! You can get a very good picture even if the RF/IF sections in your receiver aren't at their best. Hopefully the picture on the screen will tell you where to go next.

Keep an eye on any wax paper decoupling caps on the heater chain as if any of these suddenly decide to go short they could really spoil your day by taking out / stressing a load of filaments.

Good luck!
