[Amps] lots of 813's and 872a's

[LU4HMF]

Hello everybody ,
                              recently i received a huge amount of radio 
materials , including these tubes , i have a couple circuits where i can put 
the 813's to use , but dont know what to do with the 872a's
any amp circuits using 813 are wellcome , and any ideas on the 872a's will 
be wellcome too , any help would be really apreciated
maybe a desk lamp ?
i have as many as 20 813's and about 40 872's
maybe 40 desk lamps is too much i have not so many desks



73 and happy new year
