Capacitor recommendations for valve amps.

[DarrenHW]

I recently picked up a Armstrong Model 222, it's in good working order and the construction is simple enough that I'm confident servicing it myself. Capacitor replacement seems to be the most appropriate place to start so I'm after recommendations for budget replacement capacitors please.

Hi Darren,

For budget poplypropylene use these:

i wondered what you'd been upto, is this your first project since upgrading your 44's?

Thanks both, your reply's made me realise I need an assortment of capacitor values and types, I'll post a list of everything that's in the Armstrong.

Work is what I've been up to lately. I've been chipping away at some other projects during the meager amount of free time I've had over the past 4 months. I've fitted new tweeters and reworked the crossover in the UL8's I use as surround speakers and I'm currently working on a pair of Beovox 5700's to use as a centre, my to do list is still massive but I just don't have the free time at the moment (I don't think I've done any work on the 401 in a year :(). This is a project for my brother, he's just broken his wrist and he's signed off for the next couple of weeks so looking for something to keep him occupied.

Although I've not been active on here I have been keeping up with recent threads, I see your 301 is moving on nicely and it seems you've been impressed by the modded Lentek?

I'd immediately replace ALL the carbon resistors in that thing.
Most assuredly those will have Drifted due to Age and Heat. Nature of the critters.
Likely causing a significant sound change/drift from when New.
Surprisingly so when experienced.

I've not had the pleasure of any Beovox speakers ;) The fact that you've not had much to do on the 401 is reassuring in a weird way, they are so well built you could probably leave it another 5 years and it'll probably still be as good. My 301 is nearing the end of it's journey TBH, maybe decouple the motor, discrete vibration isolation and a new plinth and then it's done. It'll probably be arms, carts, platter mats that will then change over the years. The Lentek is a side distraction TBH, it is very good and I bought it on a whim, it's a keeper for the time being and works well with the Denon 103M that I bought. I must admit that I've been messing around with Tuners as well and I fancy getting a Troughline 3, I have a Dynalab but fancy something to sit in the valve system. Good luck with the Armstrong Resto, I look forward to following this thread.
