Mastersound Tube amp

Trying to swap 845 tubes on Mastersound 845 Compact amp but having difficulty removing the 845 tube. I don't want to use excessive force just in case there is a specific way of doing it. 
Does anyone know exactly how to do this? The manual is completely useless here. Does it need to be turned in a particular direction before pulling out? 

I tried contacting the distributor but have not heard back yet.

It doesn’t turn counterclockwise, at all. I’ve been getting many responses and they all contradict each other. Please respond if you own the amp.

kot, is it sideways or counter clockwise ? I’m confused. Look inside where and which stripes ? Do you mean look inside a tube ? There is nowhere else you can look inside. Please elaborate

I got it to work. Seems the standard 845 tube comes out by turning counterclockwise 1/4 turn. Replacing it is opposite, 1/4 clockwise turn. People who suggested wiggling it side to side and back for froth have clearly never handled 845 tube. I think it’s irresponsible to comment and give a wrong advice when you never handled this type of equipment. I nearly broke my amp listening to some people here with over 2000 posts.
