National company HRO 500 bands three and four calibrated and mostly dependable for using now

So I was able to finally calibrate band #4. The previous owner had broken a hex slug in an IF looking can which was the "L" part of the LC circuit for band #4. Was able to get a new slug
from an "HRO 500 junkbox" that I paid $79 for on eBay.
With that new slug I was able to calibrate band #4. Band #4 also had isues
with the 2nd wafer back. So I cleaned that wafer up for the third time.
The Synth Spectrum Harmonic Generator looks to be holding its own and working
well from the R&R I did on it the night before.
Of concern is the fact that the HF oscillator has LOW output on band #4 and lower on band #5 and almost NO output on band s 1 and 2.
The HF oscillator goes up to 33 Mhz band for bands 1 and 2 and has low output there.
Wouild the solution be to add a buffer amplifier to the VFO stage and feed that to the
Synch mixer?
I would like a consistent HF oscillator wave of constant amplitude on all bands and at all
frequencies needed.
Tall order I know.
I also found that the bistable circuit that rectifies the saw tooth wave to light the out of lock light
was OK.
Issue was my LED burned out!
Added a new LED and increased the LED bias resistors to about 800 ohms in series with the LED.

Nice work
