Default Troubleshoot 16LS Amp Kit

Hello I need some help from tube world gurus on troubleshooting 16LS kit.
I am new to tube amps sorry for basic questions. I read lots of posts on 16LS,mostly reviews and some upgrades but did not see many posts on how to fix some common problems with Tube amp. My 16LS kit is mounted in aluminum case and some upgrades, RCA and speaker plug and vol control because kit one was scratchy.

I built a 16ls kit and set of speakers 4ohm and have notice 2 problems:
1. a slight noise like some radio or humming can hear it only near L/R speakers both make same noise.

I think this may be some ground problem or loose contact.

2. Initially amp sound good but after 5-10 min of music left speaker start popping and sound level goes down like popping scratching noise only on one side. Right channel works fine no such distortions. After popping stop it play normal but left side sound is notably reduced.

This kit is new and I do not suspect any old parts or tubes so do not know what the problem can be or how to fix it. My initial suspect is faulti capacitors some delay discharge or power supply problem, but why only one side?

Help troubleshooting and advice on parts is appreciated.

Hi folks, how are you?
I'm planning to adapt the tone control K-TL to my K-502 amplifier, so i ask if it will work properly. Anyone have tried this?
And i would like to ask if anyone have the schematic of the tone control, so i could purchase the components and assemble it by myself.
Many thanks!

obs. sorry for my poor english, 'im brazilian!

New at forum. What a great source of information. Anyway: just built a 16ls tube AMP from tubedepot.com. Along with that a tube RIAA and a input selector.

My question is, Can i use common Ground for these three components.? Im having a bit of hum and hf noise. But at This point All the components are exposed and whitout a chassis. Before i begin to do some mods i'll try with the grounding and chassis.

Thanx a lot in advance.

Best regards
