Hi Art the circuit board in this unit is a ENH-121 I 'm not sure if it is similar but I can try that diode and it may work. Thanks for the reply Alvin From: "art bevilacqua" <abevilac@xxxxxxxxxxxxx> Reply-To: techassist@xxxxxxxxxxxxx To: <techassist@xxxxxxxxxxxxx> I don't have that particular schematic, but I do have RX-403bk. You might check to see if your power amplifier pc board is an ENH-145, if so, D816 reads out as a MTZ13JC Art Bevilacqua Essex Radio and TV -----Original Message----- From: techassist-bounce@xxxxxxxxxxxxx [mailto:techassist-bounce@xxxxxxxxxxxxx] On Behalf Of Alvin Rose Sent: Tuesday, November 20, 2001 7:13 PM To: techassist@xxxxxxxxxxxxx Subject: [TechAssist] jvc rx-401bk stereo amp Hi Techs We have a JVC stereo amplifier rx-402bk with a shorted Zener Diode ..D816 There is no number on it and I do not have a schematic..Can anyone advise me what the part number or zener voltage for this diode is...Your help would be appreciated.
