I can't remember the fuses as I never had to replace any of them. The PA5mk2 was different sonically to the original and was more like the PA7 in miniature I remember.
I'm suggesting using the CA5 II as a phono stage only and taking the fixed level tape out to a passive preamp for volume duties*. If the interconnects are low capacitance and less then 2m or so, I'd suggest a clearer sound could be achieved and with real front to back air and space...
* It's my view and from experience that many 'active' preamps in the 70's and 80's actually got in the way of the signal and altered the sound quite noticeably from input to output. The thing is, many US based audiophiles got used to the more rounded tones of their beloved valve gear that hearing a preamp that did nothing (as much as possible) to the signal passing through it caused great distress and accusations of harshness, which actually wasn't there. In the late 80's it was common to use a warm and soft toned (but still clear sounding) ARC valve preamp to match the increasingly harsh sounding and baking-hot running 'bigger' Krell power amps of this period, which were as nasty in real terms as many basic PA amps, just far hotter and far more expensive. I thought Krell came back with the plateau-bias models and I remember falling in love with their first FPB models, which really were amazingly good, but I digress. Obviously my opinion based on experiences at the time, and I'm trying not to exaggerate... I had an ARC SP14 for a couple of years until I heard a Croft at a third of the price at least equal it. The SP14 wasn't as revered at the time, as it sounded more 'accurate' and less 'cuddly' than previous models I recall..
I can't go on and I can't go back, I don't feel so matter of fact,
I tried and tried to make good sense, What's the good to try it all again?
