Please note: The BLF178P and BLF178XR FM pallet amplifiers were discontinued when NXP introduced the BLF188XR. The BLF188XR is offered at the same cost and it offers better performance. The BLF178P and BLF178XR transistors are still available for sale.
I've used this, along with a low-pass filter, to replace the "inners" in a failed Silicon Valley IPA unit for a Continental 816 transmitter. It works perfectly! I'll definitely be buying more of these!
