Robm321, how do you fit those ducks in your CD player :-)
The tubes are MULLARD not Mallard (a duck). Also, be careful of people selling "mil-spec" Mullards in the white boxes circa 1980's (tubes are not branded Mullard, but will have a month and year date code). These are modern junk, and will not come close to the genuine NOS Mullards from the 1970's and earlier.
