What common tubes are similar to the 6DY7? I cannot seem to find a spice model. Therefore a unit with similar characteristics will work virtually and when it comes time to build the amp, I will make all necessary changes to make it work in real life.

The 6DY7 and 6DZ7 are nothing more than two 6BQ5 tubes in one bulb.

I found two at a hamfest several years ago, and four more 6DZ7s on e-bay.

I don't know if there is an "ELL84" or Russian equivalent (???) :/ [:)

If you are from or are in the Chicago area, check this place out. The guy that owns the place has a whole case of RCA branded 6DY7 tubes he does not know what to do with. He has been sitting on those things for years. In his basement he also is sitting on a goldmine of 4000 tubes of various types. It was him I bought the two NOS 5AR4's off of. For $50. Way to go! I even told him some of those go for big bucks on eBay. If there is a tube you want or need, odds are he has it.
