so I got this Leslie amp......help

[cozzo]

Don't know if anyone can help me here, I'm an Amateur electronic tinkerer, and all this tube stuff is new to me, been reading till my head hurts
Found me this Leslie cabinet, model 50c, did a restore on the cabinet, and rewired new 2 speed motors, new relays, etc. The amp in it worked when I got it, and I was planning on keeping it in the cab, and since it's 2 channel, gonna biamp it, which works great.
Anyways, somehow, I found out the hard way by getting shocked that I'm getting 50 volts from chassis to ground, so I pulled the tubes, and the big filter cap and started going through the 50 year old wiring trying to find a short. I wanna replace some things while digging around, and can't seem to source them. The first are the two cathode bias resistors, these are long barrel shaped resistors. I think they are made by ohmite, but can't find the specific values of 75 ohm and 400 ohm, of the 20 watt variety. The existing ones gauge out correctly on a meter, but look deformed and melted. Another thing is a transformer that has been replace already. It's too big to fit under the chassis where it's supposed to live, and looks like it already shorted on a tube socket previously. I believe from the schematics attached with this post, that it is the transformer that goes to the speaker plug marked "strings", the channel run by the 6v6 tubes. The transformer that is in it now has a marking of EMI-010975. I'd really like to know what kind of transformer this is considered, where I can get another, and can I test it with an ohm gauge for short to ground? I did and got nada. Also can tubes short to ground?Any help trying to figure out where to start on this would be helpful, as I am a novice
Thanks, Kevin

edit- heres the link schems for the amp section are in the middle

You shouldn't rule out that the short was in the filter caps. Check your grounds and then check spots on the power rail for continuity to ground with the amp off. Good luck, sh

You link isn't working and check out how long your sentences are.

I'd do it right.

Pull the amp, take and post pictures, makes it easier for people help.

Plan on replacing the electrolytics, and any resistors that look "melted". Just because a resistor measures within tolerance it can stray with real voltages and heat.

Many guys mod the Leslie amps so that they are voiced for guitar a little better or just bypass that amp and run it with a guitar head.

Leslie's are very cool and worth the restoration.

Luthierwnc- there is one big silver plug-in cap- can those leak to ground, again checked with meter, no resistance. I was planning on replacing it anyways, as it's recommended by all the Leslie vendors

Structo- Try the new link, I did an edit, sorry bout punctuation- was excited, and in a hurry

dreric- I got it out, and might post some pics later, really crowded. I just wanted a little direction on what to look for, like the filter caps that Luthierwnc suggested. Yes about the resistors- that's why I why I'm looking for some new ones. I actually found the variety at Mouser.com, but the values, I was looking for were not in stock, AND they actually carry some transformers (ironically made by Hammond) and if I'm gonna order the resistors, like to order the transformer too. I am perplexed at what it is, is it considered a power transformer? I checked primaries with an ohms gauge and got around 1 ohm, the other side measures out at .450, and ,.245 ohms to the center tap. you can actually see it is in a bad place on this vid- it's under the chassis

The one that someone else put in is encased in metal, and is too big, so it rubs the sockets, not good. When I found it- someone had put a layer of electric tape in there to insulate

Choose modern values for your replacement resistors, like 68 and 470.

reveals, that with no (power or valve) tubes, nor the filter cap installed- I'm getting 50 volts to ground- shorted power transformer?
