Question for the doctor

[ThunderOne]

Hi Doc! Since we have rather similar DR201s, can you please tell me what are the values of the 6 inner mounted filter capacitors in our amps? And which brand you recommend should I ever need to replace my old ones?

Thank you.

I wish I still had it! I had to sell it about a year ago.
but it had:
One 50uf+50uf
five 100uf+100uf

I used JJ's back when I recapped it as they were the easiest for me to find. They are OK. I believe I got them from Eurotubes.com

Antique Electronic supply has them and they have F&T's in those values as well.

I guess that Vintage HIWATT Restorations should carry the 100+100s??????? I will have to put that on the to do list!

I'm sorry to hear that you had to sell it...But I guess you must have kept at least one other Hiwatt, huh?
Many thanks for the info, Doc! I've had good previous experiences with F&T in Marshalls, so I'd like to stick to those if possible. Please let me know if/when VHR will carry the 100+100.

Yeah, I have a few HIWATTs!
I am looking for another KT88 DR201
and of course always looking for a DR405.

I will certainly get in the 100+100's

We will just put together a DR201 Re-Cap kit!

Also Doc, can you tell me if your DR201 headcase had a thin metal (tin or aluminum or w/e) sheet (some call it a "Faraday shield") nailed or stapled right beneath where the amp chassis is bolted? Mine doesn't have one and I'm wondering if this is something that should be added.

Stepping in for the good Doctor: Yes, your amp should have a shield. Most of my Hiwatts had them sort of glued down. After a couple of chassis removals, they came loose. I suppose someone got tired of trying to line up the extra holes and got rid of your shield.

It doesn't have to be much, but should seal off the entire chassis.

I found a small roll of sheet aluminum (used for roofing) at Home Depot. Cut it to fit with a utility knife and used a little silicon adhesive to hold it in place. Just like the OEM shielding.

Thanks for the info, guys!
