I would think 20A would be fine unless the run is long, then I'd opt for 30A.? Be aware that pin arrangements for the plug and socket change for the various ratings.
Even if the PS is working ok with the amp, I always replace the 5K 7wt resistor on the underside of the supply with a 5K equivalent, 20 watt rating.? When the original resistor fails, it takes out the ALC pot that also contains the standby switch; these haven't been available for decades. -----Original Message----- From: Duane Calvin <[EMAIL PROTECTED]> To: [email protected] Sent: Mon, 28 Jul 2008 2:34 pm Subject: Re: [drakelist] Drake L-4B I ran a 20A line for my Alpha 99.?
