Avi,
Don't be scared of your boiler. But do try to descale with it in first. That way you can flush descaler through the entire machine. I have a 1981- same color as yours, maybe- mine is 70's burnt orange.
You sound like you know how to do the descaling. Mix it up add to the boiler fill and heat it up, let it sit, powered up for 15 minutes or so and turn off. Just let it soak. Then power it up to temp again, etc maybe for about 4 cycles or so. At least thats what I did. I also flushed through the steam arm, pumped several shots through the group etc. I also removed the steam arm.
Top up the tank in between cycles. After you are happy with the degree of clean. Flush several tanks through.
Ciao!
