Good idea.

Since the maximum reflected current from the load is going to be

/ Vs²\
| ---- |
\ Rl /
IP = ---------- = 0.00417A,
Vp


That's gonna be a _small_ fuse!!!

Since the only thing that's ever going to happen in there is
probably a catastrophic failure, I'd use something like a 1/10 amp
3AG in case that ever happened.

Hmmm. The SB2812-1218 transformer is an 18V secondary if its
series connected, 9V if parallel. Maybe the SB2812-1204,
parallel connected, would be a better choice?
