"12.1 pushed HIGH
And 25A pushed LOW"
---------------------------------

I did not try it ^__^
Better ask Pang to do it : )

Hi, Richard.
I am in Shanghai right now. So I will try to see if I can find the "electric wood" in here. I remember seeing it before. It is not black but just very dark brown.
Also one of the amp lost the EF37 top cap. Do you know if they can still be found?
I intend to replace all resistors with carbon composite ones, i.e. Morganite or AB.

YC,

I am not familiar with Morganite.
Vintage A&B is not reliable in general.
Kiwame is also good and cheaper than RMG.

You may use the top cap as follows. Available at Ousiluk. But the 'small' ones.

rcwy hing,

＜Kiwame is also good and cheaper than RMG.

I tried only once a Kiwame 2W resistor stepping down the screen voltage of the F2a11 from B+ but I don't like it. It sounds more solid and blunt than RMA and AB without the charming smooth midrange of carbon resistors. Even a white coffin in this particular position sounds more 'fluent' than the Kiwame (although sounding quite 'sandy').
I will try them again in other position in the future.

Hi, Richard.
The white caps do not look original. I may need to look into UK suppliers and see what can be found.
The Morganite are UK carbon composite resistors. AB can be good when over-rated and NOS are used.

The Best Signal Resistor?

Over the past twenty years I have tried numerous types of resistors in almost every conceivable position in my own projects. Choosing the "best" signal resistor for your audio project is an alarming exercise and can lead to madness! The perceived sound quality differences of the various resistor types in audio circuits is, to some extent, subtle, subjective and personal. However, below you will find my impressions.

- Metal film resistors should be avoided. Most of them have the tendency to
sound "cold". Ok, some metal film resistors, including Holco, Beyschlag,
Philips and possibly some military grade types do not sound too bad, but I
always missed some of the warmth!

- Although metal foil resistors, the “High-End" choice of many audio
manufacturers in general sound excellent, I still find the sound somehow
“artificial“ and not really worth the high price.

- Also metal oxide resistors are not my preference, since they give a blurred
midrange image.

- Carbon composition resistors by Allen Bradley, Vitrohm, Morganite, Ohmite,
Xicon, Kamaya etc. sound excellent, natural and warm. They are less
unaffected by vibration. These resistors are my preferred types, although
tolerances and temperature stability are poor. There is also the issue of noise
which, to my ear, is not really prominent or annoying, not even in moving coil
amplifiers.

- Riken Ohm carbon film resistors approach almost the warmth of carbon
composition types but without the poor noise, drift and tolerances. They are
an excellent replacement for them!

How About Capacitors?

As to resistors, I have tried numerous types of capacitors and combinations of different types and values in my own projects. Choosing the "best" sounding capacitor or capacitor combination for an appropriate application requires a great deal of staying power. The perceived sound quality difference of various capacitor types, dielectrics and values is however clearly audible. Below you will find my preferences:

- Silvered mica is probably the most linear low value capacitor. They are most
commonly used in high-frequency applications. In comparison to others, they
are physically very large and expensive. I personally find the sound very good
but in some cases not really worth the high price.

- Polystyrene and polypropylene film capacitors have excellent electrical
properties, including high dielectric resistance and very low losses. They are
linear and stable, but physically large. Many of these capacitors are
metallised, meaning that the film is coated with an extremely thin layer of
vapourised aluminium. This makes the capacitor much smaller than would
otherwise be the case.

- Oil/ Paper capacitors were used ages ago in tube applications, and can still
be found in many high-end audio applications today. They sound excellent,
are mechanically robust and insensitive to vibration.

Ceramic and tantalum capacitors should be avoided at all costs for audio applications. Some popular mylar and polyester types sound ok. Most of them have the tendency to have a grainy or blurring sound . Electrolytics are mainly used as filter capacitors in power supplies. Although there is almost no alternative for supplies, I refuse as often as possible to apply electrolytics in audio circuits (except Silmic, Oscon and Black Gate types in some cases).

I don't know yet. Morganite is the UK CC resistors manufacturer but was taken over by AB in the 60s. My friend has sent me quite a few of those resistors along with the amp. I just haven't unpacked them yet. My guess it is similar to the one on the fifth from the left.
For caps, in fact, I want to try the silver foil Jensen, but they are just way too expensive...:-)

Riken Ohm feature gold plated copper axial leads, 1% tolerance, produced by depositing a thin film of carbon on a ceramic base.These Japanese audiophile resistors are considered by some to be the best for classic tube audio circuits like Marantz Model 2, Mullard 520, Acro, original Williamson, vintage guitar amp designs, too. We proudly introduce them to the American market. If you've never heard how good premium carbon resistors can sound, you're in for a very pleasant surprise! These combine the transparency of a good metal film with the warmth of vintage Allen Bradley carbon composition resistors without the noise and drift. The body of the .5w resistor is 1 cm. long and the leads are 3.5 cm. long. The diameter of the body is about 3mm. The body of the 1 watt resistor is 1.5 cm. long and the leads are 3.5 cm. long. Diameter of the body is about 6mm.

Resistors
We never thought about resistors very much. Compared to capacitors, the sonic differences between various resistors are negligible. But there are exceptions. Aside from metal film resistors from Vishai and Caddock, tantalium or metal oxide resistors from Holco, we have achieved the best sonic results with

Carbon Composition Resistors

Today they are still being manufactured in Japan, due to their good high-frequency characteristics. But the discontinued resistors from Morganite, Allen Bradley and ITT (1960 models) sound better.

yukclee hing,

＞For caps, in fact, I want to try the silver foil Jensen, but they are just way too expensive...:-)

I don't think Jensen silver will sound great in vintage amps like Leak. I have a pair of 0.1 and a pair of 0.047. I tried them in my amps and I find them working better in SETA than vintage PP amps. Furthermore, I have to do some tuning to other parts of the circuits otherwise the sound will be tightened up. I must agree that they have the silkiest and most elegant mid to high amongst all the caps I tried but they sound very different from TCC and they're not plugNplay type of caps.

BTW, my Klangfilm amps have Bosch MP oil caps throughout for PS and coupling and I'm trying to substitute them with TCC one by one to see what difference it makes.

When replacing with modern caps, most likely the value needs to be adjusted.
