resitor networks, any reason not to use them?

Im using some Bourns metal film resistor networks in my prototypes, they are nice and tidy on the board for summing duties in an audio mixer, they are rated for 200mw at the moment Im doing a simple mixer, 4 stereo channels so 2 resistor networks, 4 elements each with pin no 5 as the sum. I presume ...

Re: Behringer Time Machine modulation rate mod?

If I replace all the jacks* is there any reason to use TRS ? they dont appear to have any benefit since its not battery operated and theres a separate on/off and on/bypass switch

(Im doing a dual rehouse)

Re: Behringer UV300 - rehouse with all functions intact

Thread necro, but I did just this using standoffs to keep the existing switch and pots Fits well into a 125B. I added an extra switch to parallel a 330nF with the 47nF at c15 for extra slow mode.
