Parts indecision about ASR (was: Re: [sdiy]: a good panel partner for Analog Shift Register)

[anthony]

I have been meaning to make a double version of Ken Stone's ASR for a long 
time, but it seems like all of the good caps I have in numbers sufficient 
are either too large or too small: 6.8nF 1% tolerance polyprops and 100nF 5% 
polystyrenes. I thought about using 2 100nF PS's in series with a switch to 
have the long hold too. But I think I only have enough for 1 unit that way. 
Unless I buy some more Jim-Pak "mylar" cap grab bags. The ones at my local 
store have had a lot of these polystyrene units in them along with a lot of 
polyprops.

Another question: I guess I could order some LF356's, but would the offset 
of a TL034 (of which I have 1) or a TL054 (of which I also have one - TI 
sent me samples back in the 80's...) be lower enough than a TL074? I'm 
pretty sure the 034 would be. I could check the specs, but I d0on't feel 
like it right now. I've been submerged for so long in my tube tinkering that 
I have not made anything solid state since I made a little bass amp for my 
daughter back in October.
