N@Z 0 Report post Posted October 9, 2004 Very nice. Nearly perfect, my only comments are concerning the input & output sockets, they are a little too close to the volume knob. Do you have to remove the whole enclosure to replace batteries or can they be accessed from the rear? Share this post Link to post Share on other sites
digi01 0 Report post Posted October 9, 2004 (edited) thanks for your comments. Really,it is a problem.they be accessed from the rear,but you have to unscrewing the rear board to change batteries.in the rear board,including a power switch and a wallwart supply socket. the knob and sockets are not on the line in the same level.I reserve the space of 50mm,it can works fine. enjoys Edited October 11, 2004 by digi01 Share this post Link to post Share on other sites
huangyong 0 Report post Posted October 10, 2004 The only problem is the trouble of unscrewing everytime you need to change batteries. If make it rechrageable, it would be nice. No need to open the case, just supply DC in and it will charge the battery. Share this post Link to post Share on other sites
