I totally agree with the above.
The TenTec L-network tuners are very similar to a military Collins unit used
for random wire tuning using an E F Johnson 18 uHy roller inductor, a 500
pfd 2 KV Johnson air variable and 500 pfd padders made from 500 pfd padding
capacitors made from 5 x 100 pfd door knob ceramic caps in parallel.
The TenTec units also have a good Balun built in that I have used
successfully at legal limit power.
JMHO - Happy Holidays es 73 to all,
