Hi Level Anything – glad you liked this, If you send me a message with your e-mail I will send a link to some recordings when I get a chance to post them – may take a week or so as I’m away from home.
To set the bias I used a frequency generator on my tablet, using 25Hz, 100 Hz, 400 Hz, 1k, 6.3k, 10k, 12.5k and 16k. Plugged this in to the aux input and recorded on the UR cassette at 0dB, dbx in (can’t bypass dbx easily on the 244). Played back and adjusted the bias trimmers - the cross headed screws in a line of 4 beside the playback amp pcb) channel by channel so as to give best response after another recording – and so on until I got a reasonably flat response with good top end. Turning the trimmers anticlockwise reduces the bias current. I turned them about ¼ turn at time and about 1/1/4 turns in total. Response at 25Hz is now -3dB, which isn’t bad, 16k (+2dB) is as good as SA was. It is -7dB at 20k for both due to the dbx filters. Purists will howl but I find this works for me.
Dave – point taken about the distortion. I can’t hear any more than normal so I guess it just works for me!
