Zenith 5H40 chassis restoration.

[jaymanaa]

Hello all, I recently acquired this Zenith, and while restoration may not be the correct word, I would like to get it safely operating again (mostly for DXing fun). I found a ton of useful information here, http://www.transoceanic.nostalgiaair.org/h-500.htm , but being relatively new to radio repair I thought I might save myself some heartache by asking you fellows. As the pictures reveal, someone has made some "repairs" in the past. The multi can was replaced by a tubular lytic of all the wrongs values, and it looks like the two caps (one lytic and one film) with the green spaghetti on them were also replaced. My main question is this; On tube Hi-Fi gear, which is my main hobby, I normally just replace pretty much every cap, diode, and resistor. I have a feeling though, that the same approach here may affect the operation in a detrimental way, in regards to alignment. However, I also feel that a radio of this age, probably needs an alignment anyway, and I would have to send it to someone for that. I have a tone generator and scope but that's about it. The radio is in good cosmetic shape, so all it really needs is electronic work. Any ideas or advice on how to approach this would be very much appreciated. I re-capped a Zenith console from the 30s years ago, but it worked well enough in my upstairs room with it's built in wave magnet, that I didn't worry about alignment. I live outside Kansas City and my main goal is to listen to the Grand Ole Opry out of TN on Sunday nights. Thank you all very kindly in advance.

Edit- And the selinium rect. has also been replaced. I was wondering if I could use a single uf4007 diode there, or would I need to account for the increase in voltage due to the lower drop of a modern piece?
