Backwards for a throwout bearing (TOB). The fingers are away from the TOB when the pedal is up, and the TOB does not spin. If you have free play in the linkage when the pedal is released, the TOB does not spin and will not be noisy.

If it's noisy when the pedal is released and you have the proper free play in the pedal (ca 1" free play at the pedal), it has to be the input gear or the countershaft. The most likely culprits are the front main bearing or pocket bearing in the main drive gear.

Suggest you read the thread I posted above, where my T-18 had similar symptoms.
