I have a Nak LS-5 I still use
I use Maxell XL II tape exclusively (best bang per buck)
I still make tapes for the car on occasion
You can pick up an 8 pack C -90 brick for $9 at Sam's Wholesalers
I used to bias tape decks using the Nak analyzer,
If you have the bias controls on the 505 (sorry I can't remember if that came on that machine - past my time)
the Maxell tapes were a -1 bias versus TDK and Nak SA tape formulations on my LS5. With a three head setup, you can isolate the correct tape bias via ear using headphones and material like piano music
hope this helps
