Sorry, that machine is sadly sitting waiting to mend yet another pair of knees- summer is coming and pant knees will no longer be an issue- just bandaids. We refurbish vintage machines and my hours are spent, cleaning, fine tuning and learning each ones personality to best represent it. So- I sew a great deal( up to 15 hours per a machine) Knowing how outlandish a repair to a computerized machine is I would not run some of the things through it we do on the robust vintage ones. However, even though I was last told that specific machine was sorely outdated and worth very little ( by a dealer trying to get me to upgrade) I will stick with it,but if I run across another I'll drop it in the mail okay.
