Response is a little slow- I had to wait 12 hours to receive download link but it says that it may take up to 24hrs.
Manual is old and was not produced in PDF- scanned copy is exellent.
Overall- value for money- I recommend

Excellent quality and quickly delivered manuals at a fair price. Great care is taken in the reproduction process. Even photographs and highly detailed drawings are as clear as in the original. That cannot be said for some freelance manual copies I have obtained from the web. If you have exhausted your internet search of technical manuals, try Owner-Manuals.com. If they do not have it, I do not think it exists. Perhaps, if requested, they may be able to find it. Their resources are certainly greater than most. Shopping here certainly beats waiting for months or years for the manual you seek to appear in an internet auction or garage sale.

ADJUSTMENT
X86 Circuit Adjustment Specification (K, R, H type)
Item 1. Adjusting image detection coil L103 Adjustment Method & Value 1. Turn VR101 [RF-AGC] counter-clockwise as much as possible. 2. Impresss sDC2.0V to TP [IF AGC] (IC101 #36). 3. Input fo=45.75MHz Mod=1KHz AM60% Level=100dBµ to TP [IF] (CF1 #1). 4. Observe the waveform of TP [VIDEO] (IC101 #8) using an oscilloscope, and adjust L103 so that the output level is at the maximum.
Maximu
Condition � ANT no signal � If the waveform is clipped, raise the DC voltage somewhat. � AC range
2. Adjusting audio detection coil L101
1. Turn VR101 [RF-AGC] counter-clockwise as much as possible. 2. Input fo=41.25MHz non-modulated Level=94dBµ to TP [IF] (CF1 #1). 3. Connect a voltmeter to TP [SIF] (both ends of R107) and adjust L101 to 0V ± 0.01V. 1. Turn VR101 [RF-AGC] to clock-wide direction as much as possible. 2. Input RF signal 30dBµ 11CH color bar to ANT input terminal. 3. Audio (P/S-6dB) non-modulated. 4. Connect a voltmeter to TP [IC101 #12] and adjustVR102 [SMET] to 3.5V ± 0.05V. 5. Set RF signal 70dBµ and adjust VR101 [RF-AGC] so that the value of the voltmeter connected to TP [IC101 #12] is 4.6V ± 0.05V. 1. Connect frequency counter to PIN1 of CN5 [IC2 #7]. 2. Connect Pin3 [IC2 #8] of CN5 and Pin2 [GND]. 3. Adjust VR1 [15KHz] and set to 15734Hz ± 100Hz.
� ANT no signal
3. Adjusting S-METER VR102 4. Adjusting RF AGC VR101
� SlideVR101 so that AGC will not be effective at 30dBµ. � Be sure to conduct adjustment on the SMETER before adjusting RFAGC.
5. Diversity free-run frequency VR1
� ANT no signal
