The item received was as described, as expected. I was pleased with the order. Thank you.

Superb rendition. Drawings (schematics) complete and unabridged. I do a great deal of vintage audio restoration. Documentation is essential for successful repairs. I have found sources over the years that offer good documentation, but rarely all that is necessary. Owner's Manuals has filled that void with complete and legible documentation. They have narrowed my "favorites" to a more manageable collection. This Denon manual in particular contained the latest revisions level, and offered alterations favorable to updating the item. The Illustrated Parts Breakdown (IPB) was well enough detailed to simplify part symbols and physical locations. You will not be disappointed!

KTC-V500E/N/P
ADJUSTMENT
X25 Circuit Adjustment Specification (M : For the Other Markets) Item
1. Video detection co il adjustment L303
Adjustment method/Adjustment value
1. Turn VR301 [RF-AGC] fully to the right. 2. Apply DC2.0V to TP [IF AGC] (IC300 pin36). 3. Feed fo=38.0MHz, Mod=1kHz, AM60%, Level=100dBµ into TP [IF] (A100 pin8). 4. Observe the TP [VIDEO] (IC300 pin8) waveform on an oscilloscope and adjust L303 for maximum level.
Conditions
No ANT signal If the waveform is clipped, slightly increase the DC voltage. AC range
Maximum
2. Audio detection coil adjustment L300
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed fo=31.5MHz, No Modulation, Level=94dBµ into TP [IF] (A100 pin8). 3. Connect a voltmeter to TP [SIF] (both ends of R314) and adjust L300 for 0V ± 0.01V.
No ANT signal
3. S-METER adjustment VR300 4. RF AGC adjustment VR301
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed a 30dBµ CHINA 9CH color bar RF signal into the ANT input terminal. 3. Audio (P/S ratio -6dB) no modulation. 4. Connect a voltmeter to CN300 and adjust VR300 [SMET] so it reads 3.5V ± 0.05V. 5. Set the RF signal to 70dBµ and adjust VR301 [RF-AGC] so that the voltmeter connected to CN300 reads 4.8V ± 0.05V.
Postpone adjusting VR301 to prevent AGC having effect at 30dBµ. Ensure the RF AGC adjustment is performed after the S-METER adjustment. No ANT signal Test mode
5. Diversity free run frequency adjustment VR400
1. Connect a frequency counter to CN400. 2. Using the remote control unit TV/NAVI button, switch to adjustment mode. 3. Adjust VR400 [15kHz] so as to obtain 15625 ± 100Hz.
