Whether you have an ST-20 or ST-50 or ST-60 or the 30 watt mono version I will show you,putting film caps in place of the lytics is the smartest thing you can do.
We are all familiar with the gold electrolytic cans that Leak uses which are two section as a rule and the value is a dual 16uf or 22uf at 500v..Well one day the original cans blew it's guts out while I was listening to it in stock form.I had it for about two days and lucky for me,it made me realize that these 35uf at 500v film caps I have been using fit and push right up in there tight as a glove..You can only replace one section but you can glue the other section in in right next to it as you can see from the photo. You can also use the CDE brand but the Unlytics I know fit perfect..Anyway.the improvement is tighter bass and mids and more detailed high end..The 35uf poly is perfect in any Leak right off the GZ34.

Great solution for a great amp. I love what polypropylene film caps can do for an amp.

I plan to use the unlytics for my futterman (800uf) output couplers I think you have to send in an RFQ to unlytic and then they quote on price- there are no distributors that I know of.

My Wyetech SET 211 output amp uses an array of polypropylenes in the high voltage power supply and it is one of the most impressive SETs that I have heard.

A long time ago I put films in for the doubler for a friend's Marantz 8b Wow... I didn't want to spoil the stock look of mine so I never did it to my own amp- I might have a go at it though one day.

  This is precisely why you goop them in because you can pull the caps back out with no damage and put it back to original..You can also shove a dual 50uf at 500v F&T cap in the leaks up in that can once it's hollowed out.I much prefer the polys tho just as you do and I definitely understand the WOW in the difference these caps make.
  
  If I were you on the Futtermans,I would parallel stack 200uf film caps like Panasonic or Vishay or whatever cap you choose.You can also mod the Futterman amps so they don't need those big output couplers as in the earlier designs.
