Help returning an Allnic H1500 SE II phono stage


Looking for some feedback and recommendations for retubing my Allnic H1500 SE II phono stage that are getting long on service hours and besides like to have a full set of tubes on hand for any piece of tube gear I have in play for trouble shooting issues as they come up. The tubes in question are not readily available through the normal channel's like Upscale Audio or The Tube Store except for the rectifier tube that has been replaced with a Phillips 5R4GYS with great sonic success. The list of tubes needed are as follows, (2) E282F, (2) 7233, (2) 6485, (6) 5842. I have found them all on eBay from different sellers but not confident that is the way to go. Any help or advice will be appreciated.

What were the tubes used in this model originally purposed for? My recollection was that the E810F in the H3000 was meant for telephony switching, and was not originally intended for audio, which is why it's an offbeat tube- not expensive, but not usually carried by the usual audio suppliers of NOS (though who knows what they have accumulated). wrm57 is correct as to my knowledge, David is retired, Albert's your man. (David was great to work with, but you have to appreciate Albert's sense of humor- a wonderful character). 
If it's of any help, an older Sams tube substitution handbook I have lists some tubes that can be substituted for a couple of the types you listed:

5842:  Western Electric 417A and 417B

6485:  6AH6WA

Good luck.  Regards,

almarg thanks for that, I will keep all that in mind. Have contacted Albert Porter in the past and he seems like the guy to handle the tubes for me if I settle on the Allnic replacements but just wanted to air this out on this forum and am always amazed at the information I get from all you guys and the input is always appreciated.
