How to change Recifier Bias Selection Switch?

[brisk]

I just got Single Recto Sol head. I am trying to try EL34 and the darn thing called "bias selection switch" doesn't move. Before I break the darn thing, can anyone tell me how to change the switch?

I tried three different sets of 6L6. I am now trying to EL34 but I don't know how to use the switch.

You should just stick a pick or fingernail in there and slide it over??

don't they have a manual available?

I got one one for my Blues Angel from their site, and it's obsolete.

some of them are taped over from the factory. check and see if there's any black tape to remove, then just use your finger!
