 Subject: 
Low Level Buzzing Sound from Loudspeakers
 
 
 
 
In the event you receive a Festival 300 or 500 with the complaint “Low level buzzing sound from 
loudspeakers in all modes regardless of volume control position”,
 perform the following modification: 
 
Procedure: 
 
1.  Remove (5) top cover screws; there are (3) at the rear and (2) at bottom front of the unit. 
2.  Remove (4) back panel screws; there are (2) on the back and (2) on the bottom.   
3.  Remove (3) screws from main PCB (Tuner), then squeeze the locktab (by standby transformer) to remove 
main PCB.  
4.  Disconnect  connectors WA6,WA3,WA2,WA4, WA1,and CN-1 to facilitate turning the board over. 
5.  Unsolder C10, 330ufd/16v electrolytic capacitor located between the relay and IC3.  See location drawings.* 
6.  Replace C10 with a 330ufd/25v unit (h/k part #P5154-ND). Observe polarity. (Important: Use factory 
replacement; if substitute is used it must be the same value, voltage rating, temperature rating, and 
dimensions. Space is limited; position capacitor to avoid direct contact with IC3 regulator). 
7.  Reconnect connectors and reassemble unit in reverse order from steps 1 - 3. 
8.  Turn on unit and listen to assure buzz is absent in all modes. 
 
 
 
* (Although the schematic diagram should not have to be consulted during the replacement, it should be noted that this 
component (C10) is misprinted as C13 on the service manual schematic.)
