Damaged resistors /burned/
R716/816 ? /1,5K/
R717/817 ? /2,7K/
R718/818 ? / The first number 3 / orange /

What is the correct resistance?

Could start with a 3.9Meg, then 390K, then 39K, etc. (or 3.3Meg, 330K, 33K) until unit works. Old-time resistor "decade box."

Above presumes resistor is the "only / last" part that needs to be replaced.
