Diamond gzv 4000 service manual2/15/2023 The ALINCO DM-330MVE is the European version with the CE Approved label, it works on the 220V I now use a Commercial DuraComm 55 Amp Switch mode supply from Tessco and all is fine. Several hams have complained about power supply RF noise but if your antenna or unshielded leads are close to the shack then you should be using an analog type of supply. The power supply is a nice size and the metering is nice but its basic function should always be met. I noticed the problem with my scope and the power supply un-regulation was what was causing the problem. This power supply is rated for 32 amps peak. On power peaks it was going into shutdown at 20 amps. Finally I switched power supplies and it turns out the problem was in the Alinco DM330MVT unit. I used several transceivers including HF mobiles and your large base HF rigs. Nothing to pronounced but nothing to be proud of in the audio department. Over the last three months some hams have noticed fusses on my HF Audio. I use it to power my TS-570 S/G HF transceiver and my various VHF and UHF transceivers. Well, I have had my supply about two years.
