Ops!
I wrote something wrong! They are ECL82, sorry!!
Beautiful amp nonetheless!
Ciao!
Relly interesting!
I red wonders of this little tube (E/PL82): matched with E/PC86 as a preamp tube and in SE triode configuration can give the most beautiful 0,5w ever.
Or so it's stated on "high sensitive" a german book published about 11 years ago.
Can you share the scheme and your listening impressions?

An externally hosted image should be here but it was not working when we last tested it.

Hey, my favorite valve
Keep us posted on the results. Do you have different brands of 813 / QB2-250 to try?
thanks, the tubes in the picture are used GE brands, i will use the RCA nos in my final build..
Dolphin123: always like to see something a bit different. Too many amps look to plain. Nice job and nice reds. Which is the front of the amp?
The EM84 indicator (I presume em83) is probably facing forward?
Very nice indeed!

Sure, EM84 is facing forward. Second phtoto shows the front.The EM84 indicator (I presume em83) is probably facing forward?

Thanks guys.
Hi, my last SE EL34 amp - no NFB and triode configuration. On the occasion of Easter - my best wishes of prosperity - Dinkers
Nice JBL. Thats the 123woofer,correct.
Thanks.
That's well laid out and stuffed to the brim. Very nice work!

Yes, the JBL 4110 woofer works 123A. By the way I present my new project SE KT88 monoblocks. Regards Dinkers

A quick and dirty build. Initially wanted to add a lightspeed as attenuator. Hence the holes in the front. Alas not enough space. I'm very happy with the sound of the RH84. Especially as the output transformers were little 10$ jobbies from Triodeelectronics I bought yeaaaars ago. Very satisfying to build something relatively frugally and have it turn out so well... soundwise. Here still pictured with Russian made EL84. (Not the EV version) which have now been replaced with JJ which were slightly better sounding imo.

It looks great. I am sure you have considered that the lightspeed can be controlled outboard. The only thing that needs to be in the amp is the pair of LDRs and the 100uf caps on each channel. I used CatV cable to run to a separate box with the PS, reg and Pots. You can still get the great sound of the lightspeed in tight quarters.
Thanks for the idea. Might just order some more LDR's because I don't feel like desoldering them from the current pcp.It looks great.

Impressive at least. Haven't ever seen something like that before (OK, I'm a newbie at tube stuff, just one year on it... )Hi,
Some pictures of my current amp.
Used Tubes:
input :Standard 4019A
driver: Western Electric VT-25
power: Full Music PX-25 mesh
Rectifiers: half wave Klangfilm KL75303 (Telefunken RGN 1404)
All tubes are connected with interstages, the rest of the transformers you see are chokes.
The amp has double power channels; one for mid/high (actively filtered), one for low frequencies. The channels are split after the VT-25 with two interstages (primary in series) to drive two PX-25 into two permalloy output transformers.
Volume control is by a transformer with 24 sec. windings. the counter tubes indicate the volume setting.
Front is made from maple wood, knob from thuya burl wood, rest is Padauk wood.
High risk of un-matching themThanks for the idea. Might just order some more LDR's because I don't feel like desoldering them from the current pcp.
