I'm restoring a Heathkit AT1 transmitter and need the following RF chokes

1.1mh
qty 2
Heathkit P/N: 45-4
One is in the Plate of the 6L6 final amplifier and the other is in the cathode to ground of the 6AG7 oscillator
The manual's part listing does not give a voltage/current rating, just the value of the choke

90uh
qty 1
Heathkit P/N: 45-7
This one is in the plate circuit of the 6AG7 oscillator
The manual's part listing does not give a voltage/current rating, just the value of the choke

If any one has good replacements for these chokes, contact me off group (email address good on my website)
