Gas Boiler - Gas valve buzzing loud!

in Gas Heating
Hi All,
I have a low pressure steam system with a gas boiler. Last year at the start of heating season, there was loud, and I mean hear it throughout the house loud, buzzing coming from the boiler right after start-up. As soon as the burners lit, the gas valve would begin buzzing, when you touched it, you can feel that is where the noise is coming from. After turning the valve on and off a few times it stopped and never came back, until yesterday.
First heat call of the season and it started buzzing again, only this time, I cant get it to stop. I have searched through posts and some say its not big deal, others say it was a relay, yet others just replaced the valve. I dont want to just throw parts at it, can anyone help me diagnose this issue? Below are pictures of my stuff. Thanks in advance!

I will post one tonight, but it is very buzzy, very loud. It does not sound like a standard electrical hum.0

Sounds just like the issue I had with either the same, or a very similar gas valve on my boiler.
I replaced the gas valve as I was concerned it would fail.
Here's a thread about a similar issue with a standing pilot style gas valve.

Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.
