Reel to reel

Orpheus10,
 I wish I could help but when I purchased my 1506 in '84 at a hole in the wall used hifi gear shop in Lawton, OK while in the army, the soldier selling it via the shop did not provide with feet, all 6 selector switch plastic covers were cracked and barely hanging on, and most importantly, it did not come with a manual.  I used Maxell UD-180 10.5" tape reels exclusively and I experimented with the positions of the bia and equalization switch positions.  Right or wrong, I left both on 1 at all time as it seemed to provide the best clarity for all frequencies.  Not very technical, I know, but all I can offer.  I'm glad Benjie was able to step in and provide the proper settings for your tape selection.

I now have the owners manual AND service manual in PDF form.  I'm sure will be quite knowledgeable about the deck I've owner for 35 years when I've complete the refurb.  Until, I will defer to others, like Benjiie, who are better informed. 
Good luck! 

Thank you for the kind words Uberwaltz.  Appreciated.

Gusser, I hope you can help me; I'm looking at page 9 of the RS-1506 operating instructions, where they have the bias, and equalization chart. I'm trying to translate this for new tape that's not listed.

This is the tape I'm purchasing;

Now I'm trying to figure what bias and equalization I set on the RS1506 for this tape?

clio09, thank you, appreciate it.
If that Otari is as good as it looks, the price is right. You don't save $1k when you go with higher end R2R deck. Technics transport is smoother than Otari ? Are you sure, that's unexpected ?

Thank you Benjie, knowing the bias and EQ before I buy the tape gives me the consolation that I'll get good results.

Gusser, I'm glad you have the proper paper work, now you'll get the best results. That will help you enjoy your new deck even more.

Inna:   Yes, it is!  It is near new in appearance and operation. Quite exceptional since it was built in 1986.  RE: tape transport.  Just my HO.  I have spent minimal time with the Otari and should reserve judgement.  I am awaiting a replacement integrated amp, (Decided toobs are not for me... back to solid state) which is arriving today.  Hope to spend more time with the MX in the coming weeks.  I may find I am mistaken.

orpheus10:  I believe I have confused you.  The Otari came with all documents, provided by Mr. Wall.  I have owned the 1506 for 35 years and all this time without an owners manual (or feet for that matter).  During the refurb, I will take the time to read and learn the significance of the Bias and Equalizations switches and how they relate to different tape types.  Appreciate the input.

I know I'm repeating, but there is a good reason; while you don't need new caps all throughout the deck, they will greatly enhance your recordings if installed on "input" and "output". Get the best electrolytic capacitors available.
