Crackle and hiss on some albums

The hiss is your phono stage. Nothing to do with turntable or cartridge. If you have very sensitive speakers and high gain amp you’ll hear even more hiss. Your tube gear is what it is. 
 

As to crackles and pops - usually dirty vinyl with static or damaged grooves will cause that. Ultrasonic cleaner works great on new records. And helps with static. 
Older vinyl I would recommend washing as well if you had never done it. Either manually in something like the knosti disco antistat or using ultrasonic. Better yet both - manual wash then ultrasonic bath. Re-sleeve records in a brand new anti static sleeve like mofi or hudson hifi rice paper options. Great protection and mitigates static. 

Check your cartridge alignment as well. Tracking too light can exacerbate noise and distortion. With Rega cart on Rega table make sure the cart is installed with all 3 screws to get proper alignment. 

Everything that you need to know can be found somewhere in this thread.  The problem is that not all the information can be found in one post.  Here in one place is a summation:

1.  Not all records are created equally.  Some are noisy even when new because of a) they were made in a dirty pressing plant b) poor QC c) poor vinyl d) paper sleeves.

2.  Every record new or used should be cleaned before first play.  Wash it if it has finger prints, peanut butter and jelly etc., otherwise ultra sonic is good.  Best of all is vacuum machine first, then ultrasonic machine second.

3.  Some records with still be noisy even after thorough cleaning.  Check your stylus.  Is it clean?  Is it worn?  Is it properly aligned in terms of azimuth, zenith, and VTA?  If all of this is Greek to you, it would be best to seek professional set up help.

4.  Some records will be noisy even though they are clean, the stylus is in good shape and all is properly aligned.  At this point you still have options:  a) you may simply have a bad copy of that particular record, replace it b) the Sugar Cube is a digital click and pop filtering device that costs about $300 and does a remarkable job of removing noise in most cases c) you could give up and listen to the cleaner, but decidedly less satisfying versions of many albums available from digital sources such as streaming.  

5.  If any of this is unclear, or you have questions please ask.
