Heathkit GR900 color set

[Ray Sieracki]

Just brought a heathkit GR900 home today. It 's a 1 owner , and also came with the original asembly books , troubleshooting and other paperwork It also has a special order cabinet as apparently it could have also been put into a home built, or wall installation. I was told it was taken out of service in the 1980's and had a new 25VADP22 matrix tube installed before it was retired.
As I have not seen many Heathkit tv's, I find it looks like it was made to service , with a swing out chassis. It also has a service meter built in to calibrate circuits
My question is is this set worthy of a restoration. The chassis is in pristine shape as well as the cabinet , both were wrapped in a thin plasitc wrap for protection. In a day or so, I shall test this picture tube with my B&K.
and look into the HV cage for starter's .
I am not really into rectangular sets but this one is different, I appreciate your opinions and knowledge on this or other heathkits.
